PLEASE READ BELOW FOR HIDDEN FEATURES...

  Virtual Calc 0.9 Beta is a calculator that supports
unlimited digit capacity, customizable symbols, and variable
bases (from 2 on up).  Virtual Calc runs under windows 95,
and has a gui interface that allows you to enter equations
using mouse clicks or keyboard.

  Increase/decrease the base and experiment with various
numeric systems of infinite precision accuracy.  Try base 3...
210+210 equals 1120.  Multiply, add, and subtract large numbers
without worrying about numbers being rounded off.  Remember,
this calculator crunches big numbers...  (try multiplying
10,000+ digit numbers!)  So a click accessable memory storage
is provided for those extra long numbers.  It also supports
precedence usings parenthesis. In addition, the symbol
representation can be modified...  For example, 123456 can
be changed to abcdef, so 123+123 becomes abc+abc, and the
answer would be bdf.

  Before continuing, please note that Virtual Calc is not free.
After 30 days evaluation period, you should purchase this
product by mailing a payment of US$49.95 + tax made out to
Po-Han Lin, and send it to the address above.  Those that paid
for this beta need not pay again for all future versions of
this product.

  Now for the hidden feature: Right click on buttons and
input/output area to customize and get access to different
aspects of this program.  Note that the calculator is resizable.
Increase/decrease the base and experiment with various numeric
systems of unlimited digit accuracy.  Multiply, add, and
subtract large numbers without worrying about numbers being
rounded off.  This program can handle numbers with 30,000
digits! (limited only by the input edit boxes).  Note that
division is currently disabled and being worked on.  Look
for version 1.0, which will support division, calculating
from files (removes the 30,000 digit limitation), and tons
of extra features.

  I hope this Virtual Calc is useful and helpful to those in
the science and math disciplines, or those that are just
plain curious.  For those interested, the source code is
available for a fee (contact me through the email address
above.).
