KALKULATOR - VERSION HISTORY ============================ VERSION 1.44 - 96/12/08 A Result Variable can be now assigned to every expression; this makes chained calculations easier. The Expression Line now stays highlighted after an expression has been evaluated; its contents will be erased after any new input. Introduced a simpler method to add a regression line to an existing graph canvas. The graph Undo button now works as a toggle. The tabbed control widgets in the Main Panel have been reworked (somewhat different look and feel). VERSION 1.42 - 96/11/20 A new feature: simultaneous function graphs of any combination of expression lines, with joint min/max evaluation. The Main Panel buttons (and some others) have been replaced with a different button type, using significantly less of Windows' resources (especially important for Win 3.1 users). General cleanup of the help file. New update and upgrade policy: all free for the lifetime of the program, without version limit. VERSION 1.40 - 96/11/05 A major new feature: computer math operations, including conversions between binary, octal, hex and decimal, also 8, 16 and 32-bit word lengths. The Linear Algebra and Polynomial Root panels are now called from the new Extras menu (their buttons are no longer in the Bottom Line). For users whose email programs have problems handling file attachements: Kalkulator will now create a registration key file when you enter your key code obtained in email (in mail, by phone, etc.) The missing exponent in the Boltzmann constant has been added. VERSION 1.31 - 96/08/29 A bug fix: no more locking when a data buffer is sorted while scrolled down (16-bit version only). The default directory for statistical and linear algebra files is now always set to the Kalkulator home directory, which could not be the case if the program was executed from a third-party shell (registered copies only). New topics in the HOWTO.TXT file. VERSION 1.30 - 96/07/15 Problem with saving multiple .kal files has been fixed. VERSION 1.29 - 96/06/23 There is now an option to keep Kalkulator window on top in the Mini Layout mode. The Escape key no longer closes the graph panel; use Enter. A check has been added against too narrow plot limits. A bug occuring in data point insert operation in the XY mode has been fixed. VERSION 1.28 - 96/06/12 The definition of harmonic average has been corrected. Small touch-ups in the program and in its Help file. VERSION 1.27 - 96/05/29 Fixed problem (?) with screen fonts on some systems. Small changes in how Data Grids handle errors in user input. New ordering information in the Help file: HOW TO REGISTER BY PHONE, FAX OR ON THE WEB USING A CREDIT CARD. VERSION 1.25 - 96/05/14 An autoscroll option has been added: the Expression line will scroll to the next expression slot upon a successful computation. A [Clear] button has been added to the Root Panel. VERSION 1.24 - 96/04/22 A new feature: finding real and complex roots of polynomial equations with real coefficients (linear, square, cubic; also quartic in the registered version). Pressing the F1 key will now bring context-sensitive help in most of the dialog boxes. VERSION 1.23 - 96/03/31 A bug, introduced in V1.21 has been fixed: Kalkulator no longer refuses to do sums and derivatives. VERSION 1.21 - 96/03/18 32-bit: first release for Windows/95 16-bit: brought in sync with the 32-bit version VERSION 1.20 - 96/03/12 A major new feature: linear algebra operations (matrix and vector algebra, matrix inversion, systems of simultaneous linear equations). The editor for data buffer has been redesigned: now it uses a data grid. The maximum length of an expression has been increased to 72 operands/operators or 120 characters (registered copies). The reciprocal function has been renamed from inv to rcp. A bug fix: no more lockups when the user attempts to perform column-wise data buffer computation if arithmetic errors occur at some of the points. VERSION 1.10 - 96/02/12 A maintenance release (despite round version number). Fixed bug causing non-rounded display of some values describing plots in log scale. VERSION 1.09 - 96/01/14 Sound effects added. Important ONLY for some European users: a "." is now used as the decimal point, regardless of regional settings. VERSION 1.07 - 95/12/14 Expressions, not just values, are accepted wherever numerical input is expected. A "Mini Layout" option introduced. Physical constants added. VERSION 1.04 - 95/11/25 Workaround around a compiler bug, affecting user functions. VERSION 1.00 - 95/11/11 The original release.
