"bravo!" (16 bit) is a scientific and trigonometric calculator. It uses the  Reverse Polish Notation (RPN).

It has ten data storage registers, in addiction to the 8 automatic registers where most calculations take place.

It has 5 functions, each with a different layout of calculator's keys:

normal functions: give you the ability to quickly and easily handle simple arithmetic operations such as adding, subtracting, multiplying and dividing, as well as more sophisticated functions such as logarithms, exponents and trigonometric calculations.

Calendar functions: handle almost all the operations of the normal functions (not the financial operations) as well as calculate the calendar date of a certain number of days in the future (or past), the number of days between two calendar dates and actual days.

measures converter: a window where you can convert a number between many measure.

equations solution: let you solve equations up to 4th order.

vectorial and complex numbers calculator: let you simply handle arithmetic operations with vectors a nd complex numbers.

You can navigate between the three functionality without erasing the prevoius values.

You can, while working, see the contents of the 8 working registers, the lastx register, the ten storage registers and the 5 finance registers.

You can also use a notes where you can write and that can also be saved as a text file.

Fast all calculator functions are accessible from the keyboard.

Other programs:

einSTein: it's the most complete calculator of the series. Mathematic, trigonometric, calendar and financial functions. It can solve also irregular cash flows in a very easy way. You can save and print your data. With measure converter. Registration fee: 35 US$ (60.000 lire or 60 DM).

All the financial and mathematics functions of einSTein, without the trigonometric functionality and without the measure converter are available as a stand alon program (name: aSSo!, registration fee: 50.000 lire (30 US$ or 50 DM)).

The higher financial function of einSTein is available also as a stand alone program (Name: inTer, registration fee: 15 US$ (25.000 lire or 25 DM)).

The measure convert function of einSTein is available also as a stand alone program (Name: meaSure, registration fee: 6 US$ (10.000 lire or 10 DM)).


Reverse Polish Notation
REVERSE POLISH NOTATION (RPN)

The technique, called Reverse Polish Notation, or RPN, requires that when you perform an operation on two numbers, you must input the two numbers first, then specify the operator or function.

For instance to add 5 and 3, you normally enter the numbers and operators in the following order:

YOUR INPUT	DISPLAY SHOWS

5	5

+	5

3	3

=	8

Using Reverse Polish Notation, however, you enter the operator last:

YOUR INPUT	DISPLAY SHOWS

5	5

Ent	5

3	3

+	8

The last number, 8, is now ready to start a new calculations. For instance to calculate (5+3)/2-1, use the following sequence:

YOUR INPUT	DISPLAY SHOWS

5	5

Ent	5

3	3

+	8

2	2

/	4

1	1

-	3

For one number operation such as sin, cos, etc. you need only input the number and press the desired function button.

One common difficulty is in entering a negative value. Remember, the -(minus) button is an operator, and will seem to have unexpected results when used as you would on a standard calculator (e.g., -5 to input negative 5). With RPN, you must enter the number as a positive value, then use the CaS button to make it a negative value.

During the calculations the numbers are stored in eight automatic memory registers, called X, Y, Z, T, R, S, U, V.

The memory stack, compoused of eight memories "stacked" on top of each other, allows the automatic storage of seven intermediate results. Thus your calculator simplifies even the most complicated problems.

A full understanding of the automatic memory ist not necessary to perform simple arithmetic und financial calculations, but i strongly encouraged you  to optimize your use of the calculator by reading the section 'Registers'.


Standard functionality
STANDARD FUNCTIONS

THE OPERATIONS BELOW DESCRIBED ARE THE SAME FOR ALL THE CALCULATOR'S CONFIGURATION. FOR THE OTHER CONFIGURATIONS IT WILL GIVEN AN EXPLANATION ONLY FOT THOSE KEYS THAT WILL CHANGE.

The Standard Functions is the calculator's configuration that appear initially by default.

NUMBERS

To enter a number you must press the numerical keys.

NEGATIVE VALUES

Enter the number as a positive value, then press the CaS button to make it a negative value.

ENTER

Pushes the displayed value onto the stack for use in a subsequent operation. Enters the displayed value into the Y-register for use in any two-value operation. (see RPN)

EXPONENTIAL NOTATION

Press the key "SCI". To return to the decimal notation, press the key "NOR" (replaced SCI).

To input a number in exponential notation, enter the base number, press esp" and input the base-10 exponent. To input a negative base value, press CaS before pressing esp. To input a negative exponent (for small values), press CaS after pressing esp but before terminating the input.

HOW TO MODIFY A NUMBER

During input you can erase the rightmost digit of the display by pressing "←".

HOW TO CLEAR A NUMBER

You can erase the displayed number (and the X-register) by pressing "Can"

k DATE FORMAT

The date format in use appears on the top left of display: "E" for the European format (dd/mm/yyyy) and "U" for the american format (mm/dd/yyyy). You can change the date formmat clicking the menu at the voice "Date format". The change has effect on the registers of the higher financial functionnality, but not on the memory registers and on the stack registers (not used in the higher financial functionality).

GRAD-RADIAN TRASFORMATION

The key "c_gra" turn the displayed angle into grads; the key "c_rad" turn the displayed angle into radians.

HOW TO STORE A NUMBER

You can store the number on the display  pressing "Mem" followed by the number, between 0 and 9, of a storage register. You can perform the four aritmetic operations on the register (see storage registers).

HOW TO RECALL A STORED NUMBER

You can rtecall a stored value pressing "Rcl" followed by the number, between 0 and 9, of the storage register where the value itself was stored.

HOW TO SEE THE STORAGE REGISTERS

You can open, pressing "mem" ( at the right of the numeric pad) a window with the values of the ten storage registers and of the five finance registers. With the same key you can closed that window.

DECIMAL DISPLAY

The key"dec" followed by the number of decimal places that you will see (between 0 and 9), set the number of decimal places shown in the display. 2 is the default display.

NOTEPAD

You can open a notepad by pressing "Note". The notepad has a menu that permit the copy- and past-operations, and to save (or recall) your notes. With the same key( 'Note') you close it.

STACK REGISTERS

You can see the eight registers used by the calculator for the Reverse Polish Notation (RPN) by pressing "reg".

With the same key you close the register's window. That window is very usefull for people who have'nt confidence with the Reverse Polish Notation.

HOW TO SAVE YOUR WORK

Pressing "save" you save all the registers of the calculator (under any name), so you can later use the calculator in the same conditions as it was at the moment of storage.

HOW TO SAVE ON EXIT

If you want to save the dates on exit, click the voice "Save on exit" of the menu. In this way when you turned off the calculator all the dates are saved in the file "bravo!.mcd". Reopening the programm the dates will be recalled automatically. The letter "S" appears on the top left of display to indicate that the function "save on exit" ist on.

HOW TO RECALL YOUR WORK

Pressing "load" you can load all the storaged informations. The calculetor is now exactly in the same conditions it was at the moment of storage.

HOW TO REDUCE THE DIMENSIONS OF THE CALCULATOR

You can reduce the dimension of the calculator  pressing the little key upon the display. If you now checked the little option-box, you can still work with the keyboard. Unchecking the option box and pressing once more the little key lets the calculator get back to its normal size.

Left are the function keys that, in the other configurations (calendar, higher financial and trigonometric) can be different.

On the right they are also the configuration's key. Von From top:

Pressing "CAL" you toggle between the calendar configuration and the standard one. No register wird change.

On the left side are the function's keys that, in the other configurations (calendar, trigonometric, higher finance) can be different.

Pressing "Eq" you open the equations window.

Pressing "C/V" you open the complex numbers window.

In the lower row are the keys::

"OFF" : to close the calculator window and exit from this program.

"LAST": restored the previously entered value to the display. Use this to restart after an error or to reuse a value for several calculations. Wen you make a calculation that changes the value in X-register, the number in x-register is stored in LastX-register (you can see it in the register's window).

"Down": roll the register stack down, moving X (the display) to V, V to U, U to S, S to R, R to T, T to Z, Z to Y and Y to X. (see RPN). You may rewiev the contents of the stack by pressing 'Down' 8 times (or simpli opening the register's window).

"X-Y": swap X and Y registers. Exchange the contents of the X and Y registers. Use this to store an intermediate answer in Y register, and to return it to the display (the X register) when it's needed.

"Can": clear the X-register (display).

"int": Converts a numeric expression to an integer by removing the fractional part of the expression. The original number is sored in lastx and you can recall it by pressing 'ULT'.

"fra": Removes the integer part of a numeric expression leaving the fractional part. The original number is sored in lastx and you can recall it by pressing 'ULT'.

'copy': copy a number or a date from X-register (display) to the clipboard.

'paste' a number or a date from the clipboard to the X-register (display). Attention: the number must not be formatted (no thousand separators, yes decimal point !)

In the rows above are the trigonometric keys:

"sen": sinus.

"cos": cosinus.

"tan": tangent.

"Cota": cotangent.

"aCot": inverse cotangent.

"at": inverse tangent.

"hSen": hyperbolic sinus.

"haSe": hyperbolic inverse sinus.

"hCt": hyperbolic cotangent.

"haCt": hyperbolic inverse cotangent.

"hCos": hyperbolic cosinus.

"haCo": inverse hyperbolic cosinus.

By default, angles are input as grads.

"RAD": sets the calculator to use radians for trigonometric functions. The key will change in "°".Pressing now this key the calculator is set to use grads.

"/\": pressing this key, it appears the triangle's window. In this window you can calculate all the values of a triangle (Height, size, area, angles). First you must indicate the elements you know checking the wright choice. You can choose between: one side and two angles, two sides and the angle between, three sides, one side the base and the height, the base one angle and the height.

Now can you introduce the known data. Pressing 'compute' the unknown data are calculated.

You can switch between grades and radians with the key "rad" ("°"). This key doesn't affect the calculator.

Of course you can copy or paste a number. You need only to choose the number corresponding the little window you want copy from or paste to.

"y^x": raises the previously entered value (Y-register) to the power specified by the number in the display (X-register).

"e^x": calculates natural exponential, where e is approximatly 2,71828 and x is the variable exponent.

"/¯x": computes the square root of the displayed number (must be positive). For higher root you must use the function y^x: for instance the cubic root of y ist y^(1/3).

"Ln": computes the natural logarithm of the displayed number..

"Log": computes the common logarithm of the displayed number..

"%T": computes the percentage thet the displayed number is of the number in Y-register. Example: a company has sell for 560 millions in America and for 72 millions in Europe. Compute the percentage that the European sales make on the entire sales (America + Europe):

560

ENT 	(enter the first number and separe it from second number)

72

+	(total sales)

72	(european sales)

%T	(compute the percentage on the entire sales)

"D%": computes the percentage difference between the previously entered value (Y-register) and the value in the display (X-register). Example: compute percentage change between 34.500 and 38.900

34500

ENT 	(enter the first number and separe it from second number)

38900

D%	(computes the percentage difference)

"%": computes X percent of the value in the Y register. Example: compute 12% of 450

450

ENT	(enter the first number and separe it from second number)

12

%	(computes the percent).

"1/x": computes the reciprocal (inverse) of any rational displayed number.


Date Format

Starting the date  format is european: mm/gg/aaaa. You can change it to the USA format (mm/dd/yyyy) with the menu command 'Date format'.

Once choosed, the date format remain the same auch when you turn the calculator off.

(It's always possible to use the decimal format: dd,mmyyyy). It accepts. 02/05/1994 - 02/5/1994 - 2/05/1994 - 2/5/1994 - 2.051994.

The date format in use appears on the top left of display: "E" for the European format (dd/mm/yyyy) and "U" for the american format (mm/dd/yyyy). The change has effect on the registers of the higher financial functionnality, but not on the memory registers and on the stack registers (not used in the higher financial functionality).


Calendar configuration
CALENDAR

You open this functionality pressing "CAL". You return back to the standard functionality pressing once more the same key.

The current date appears on calculator.

This functionality change only the two rows at the top link of calculator.

In order to use the calendar functions, dates must be entered in the format you choosed, dd/mm/yyyy or mm/dd/yyyy, in the menu. You enter the simbol / pressing the key ':'.

You can calculate the number of days between two calendar dates, or the calendar date of a certain number of days in the future (past).

"D/days": press this key to calculate. You must first enter the first date (or number of days); press 'ent' to enter this value;  enter the second date (or number of days) and press "D/days".

":": when you enter a date, you must separate the day from the month and the month from the year pressing this key.

The examples help you to easily understand that mechanics


MEASURES CONVERTER

(Available also as a stand alone program. Name: meaSure, registration cost: 15 $)

You open this function pressing the key '"MIS".

You have to choose first the kind of measure (Area, lenght, etc.). After that you choose the measure you want convert. You choose it from the list that appear as you press the little arrow of the upper box.

Now you can enter the number to convert. You can get it from a register or from a memory pressing the key 'Rec' followed by the register- memory-key. But you can also key the number in with the number-key or using the keyboard or get it from clipboard using the key 'paste'.

The key 'dec' followed by a number (0 to 9) displayed the required decimal units.

Now select the required conversion in the lower combi-box and press the key 'compute'.

With the key 'copy' you can calculate the conversion and, at the same moment, copy the results into the clippboard.

You can save the results in one or more registers or/and in one or more memories with the key 'mem' followed by the required key.

'←' cancel the last digit.

'chs' change the sign.

'clx' cancel the number to convert.

'x-y' change the converting number with the converted number. the

The key 'exit' ended the program.

EQUATION WINDOW

You open this window pressing the key "Eq".

You can solve equations up to the 4th order. The equations are in the form:

a + bx + cx^2 + d x^3 + ex^4 = 0

where a, b, c, d and e are real numbers.

Once you have introduced the coefficients, pressing "compute" you get the solutions.

The 4 keys at the right site are for pasting the four coefficients from clipboard.

With  the other keys you can copy the real or the complex portion of any solution.

You can also storage the solution (complex or real) in the four double registers A, B, C and D.

These four registers are shared with the complex numbers window.

The window stay open also if you close the calculator.

You can also see the example.


complex numbers
COMPLEX NUMBERS WINDOW

Pressing "C/V" open this window.

Here you can perform complexe calculations.

The input formats are: x + yi     or      r/ß

You can toggle between the two formats with the options keys on the left (also during a calculation).

The calculator has 8 stac registers that are displayed on the top of window.

It has four memory (A, B, C, and D), shared with the equations window.

The example let you see how it work.

The window stay open also if you close the calculator.


REGISTERS

With the key "reg" You can open (and close) a window that show (in action) the 4 stack registers (X, Y, Z and T) and the LastX (LastX) register. To see the others you must click  the key on the register windows.

During the calculation, in fact, the calculator uses the stack registers in this way:

V	stores the intermediate results

U	stores the intermediate results

S	stores the intermediate results

R	stores the intermediate results

T	stores the intermediate results

Z	stores the intermediate results

Y	the number in this register it's used with that one in the X-register for calculation

X	stores the number that appear into the main display

When you key a number into the calculator, its contents are written into the displayed X-register. In order to key in another number, you must indicate the calculator that you have completed keying in the first number and that any new digits you key in are part of a new number.

You use the 'ENT' key to separate the first number from the second.

When you press the 'ENT' key, the number in the displayed X-register is copied into Y, Y into Z, Z into T, T into R, R into S, S into U, U into V.

Immediatly after pressing 'ENT', the X-register is prepared for a new number, and that new number writes over the number in X. Now the calculator is ready to perform an arithmetic operation with the two numbers in the stacks. Every arithmetic operation involving two numbers is done with the contents of the X- and Y-registers.

The 'Can' key replaces any number in the display (X-register) with zero. If a new number is keyed in, it writes over the zero in X.

The 'x-y' and 'Down' keys allow you to rewiew the stack contents or to shift data within the stack for computation at any time.

The 'x-y' key excange the contents of the X- and Y- registers, without affecting the Z- and T-registers.

Each time you press the 'Down' key, the stack contents shift downward one register. The last number you have keyed in (X-register) will be rotated around to the V-register.

Let us see now how the registers worken with a simple operation: 5+2 (in these examples only the first four registers are shown).

T	0	0	0	0

Z	0	0	0	0

Y	0	5	5	0

X	5	5	2	3

keys	5	ENT	2	-

Let us see now a multiple-value calculations:    (3 x 4) + (5 x 6)

7 x 2

T	0	0	0	0	0	0	0	0	0	0	0

Z	0	0	0	0	0	12	12	0	0	0	0

Y	0	3	3	0	12	5	5	12	0	42	0

X	3	3	4	12	5	5	6	30	42	7	6

keys	3	Enter	4   	x	5	Enter	6	x	/	7	/

You can see how the intermediate results are not only displayed, but also stored so that they are ready at the right momentand at the right place.

You can change the number stored in the stack with two keys:

X-Y	exchange the contents of the X and Y registers.

Down	rolls the register stack down, moving X (the display) to V, V to U, U to S, S to R, R to T, T to Z, Z to Y and Y to X (the display). You may review the contents of the stack by pressing 'Down' 8 times (or by pressing 'reg').

The one-number operations such as 1/x, square root, logarithm, natural exponent, etc. use only the number in the X register (the displayed number). The other stack registers dont change: change nur the X register. The earlier value in the X register wird in the UltX (LastX) register stored and you can recall it by pressing "LAST". In the higher financial function es ist used normally only the X register (save you press "ENT" or you perform a mathematic operatin). In the calendar functionality you use normally only the Y- and X regisrter.

The two-number operations such as adding, dividing, multiplying, etc., use the X- and Y register. Every time you perform a two-number operation, the results is displayed and stored in the X register, the earlier value un the X register is stored in the UltX (LastX) register (You can always recall it by pressing 'LAST') and the stack roll down: Z move to Y, T move to Z, R, move to T, S move to R, U move to S, V move to U and V remain.

This mechanism required that when you perform an operation on two numbers, you must input the two numbers first, separating the first them by pressing 'ENT', then specify the operator or function.

All that seem difficult. Initially you should try simple operations looking at the opened registers fenster.

Order of execution: you could work a problem by beginning at the left side of the equation and simply working through it in left-to-right order. All problems cannot be solved using left-to-right order, however, and the best order for solving any problem is to begin with the innermost parentheses and work outward just as you would on paper.

You can also learn very much with the examples.


NOTEPAD

You can open a notepad pressing "note". With the same key you'll close it.

You can save your writing with the menu command (in the notepad window) 'salva', bat not pressing the calculatore key 'save'.


STORAGE REGISTERS

"bravo!" hat ten storage registers, numbered 0...9, in addition to the automatic memory registers where most calculations take place. These storage registers allow you to store and retrieve data or results.

To store data to a register, use the 'Mem' funcion (left side) and assign a unique address from 0-9.

To retrieve data from a register, use the 'Rcl' function, again supplying the assigned address: the register value is diplayed and stored in the X register, X move to Y, Y to Z, Z to T, T to R, R to S, S to U, U to V. You don't need to press 'ENT', but you can immediatly perform an operation oder enter a new number.

You can see the values stored in the storage registers pressing  'mem ' (on the right side). With the same key you can close the memory window.

Arithmetic operations in the storage registers.

Press 'Mem' followed by +, or -, or /, or *, to add, subtract, divide or multiply the displayed number to the numbers currently stored in a given data register and replace the previous contents of the register with the new resul. For instance if the number 4 is in the register 3 and 5 is actually displayed, pressing the keys 'Mem' '+' '3', the number in the register 3 chang itself in 9 (=5 + 4).


ERRORS

Normally "bravo!" if an error happened, as a division for zero, display an error message. To clear it press 'can'.

An unexpected error switch the program off.

Examples of calendar computing

You enter in the calendar functionality pressing "CAL".

Example 1: determine the date 289 days before the 7/7/96

YOU INPUT	MAIN DISPLAY

Can	0,00

D/days	1.460	days

The first entered date (or days) is in the Y register, so you can still use it simply recalling it and  entering a new value (date or days). The second one is actually in the UltX (LastX) register and you can recall it pressing "LAST".

So, if you will compute the date after 3.000 days on 01/01/1997, you have to recall the date in the Y register, pressing:

YOU INPUT	MAIN DISPLAY

D/days	20/03/2005	date.

N.B.: Now in the UltX (LastX) register is the value 3.000 and not the previous date. If you would use that date, you had to stre it in a storage register..


EXAMPLE OF EQUATION SOLUTION

0 = 25.4 + 32.25x^2 - 12x^3

I introduce the values 25.4 for a, 0 for b,32.25 f or c and 12 for d (b and e are null or empty).

Pressing "compute" i get the solutions:

x1=0,12 + 0,84i

x2=0,12 - 0,84i

x3 = -2,93

Pressing "mem" sitely of x2, followed by A, I storage the value 0,12 -0,84i in A.

I can recall this complex numbers in the "complex number window".

Pressing r (sitely of x2) I copy 0,12 into the clipboard.

pressing 1 I copy -0,84 into the clipboard.


EXAMPLE OF COMPLEX CALCULATION

Let us do this calculation:

{[(25/30 + 45/0) x 30/15]/28/-75 -15/86]}^0,5

The format is already prepared.

I introduce the first number:

25	it appears in the 0 register

tab

45	it appears in the 0 register

ENTRA	the number appears also in the 1 register

The number in the first inputbox is highlighted. I can so write the new one.

45	it appears in the 0 register

tab

0	it appears in the 0 register

+	addition

The 0 register display the results of addition. The register 1 display the value that were in register 2 (and so on).

I can now input the third number.:

30	it appears in the 0 register

tab

15	it appears in the 0 register

x	multiplication

I key in the fourth number:

28	it appears in the 0 register

tab

-75	it appears in the 0 register

/	division

I key in the fifth number:

15	it appears in the 0 register

tab

86	it appears in the 0 register

-	subtraction

/¯x	square root

The result is displayed:

7,63/52,17

N.B.: When I introduce a number, it will automatically converted and displayed also in the other format.


SHAREWARE

bravo! is Shareware, and if you will use it regularly you must register it!

You can use this software for 30 days. After this trial period, if you can not continue to use it without registering it.

You are licensed to give exact copies of the original Shareware version to anyone.

You are specifically prohibited from charging, or requesting donations, for any such copies, however made.

Unregistered use of "bravo!" after the 30-day evaluation period is in violation of copyright laws.

The registration cost only 22 US$ (35.000 lire or 35 DM) that you can pay using the modality described in the following section..

Benefit of registration:

1.	you are ok with the law and feel you better;

2.	you put an end to the nag screens and opening banner;

3.	you get technical support by phone or e-mail;

When the author receives notification of your registration you will be e-mailed a registration number immediately.  However, if you should happen to register on the first day of the author's vacation it may be several days before you receive your registration number!

What is SHAREWARE?

Shareware distribution gives users a chance to try software before buying it.  If you try a Shareware program and continue using it, you are expected to register. Individual programs differ on details -- some request registration while others require it, some specify a maximum trial period.  With registration, you get anything from the simple right to continue using the software to an updated program with printed manual.

Copyright laws apply to both Shareware and commercial software, and the copyright holder retains all rights, with a few specific exceptions as stated below.  Shareware authors are accomplished programmers, just like commercial authors, and the programs are of comparable quality. (In both cases, there are good programs and bad ones!)  The main difference is in the method of distribution.  The author specifically grants the right to copy and distribute the software, either to all and sundry or to a specific group.  For example, some authors require written permission before a commercial disk vendor may copy their Shareware.

Shareware is a distribution method, not a type of software.  You should find software that suits your needs and pocketbook, whether it's commercial or Shareware.  The Shareware system makes fitting your needs easier, because you can try before you buy.  And because the overhead is low, prices are low also.  Shareware has the ultimate money-back guarantee -- if you don't use the product, you don't pay for it.
