FoxCalc v0.84 Copyright (C) Mateusz Viste "Fox" 2007


FoxCalc is  a simple  calculator for  DOS with  a text  user interface. The
program has a mouse suports,  so take care  to run your mouse driver before
launching FoxCalc, it will be much easier to use it.
It's an open-source project, so feel free to modify the source-code at your
convenience, and let me know of any improvement.


If you really can't use a mouse, there is the list of shortcut keys:

RESOLUTION
FoxCalc can  display numbers  max. 16 digits  long + 10 digits  for decimal
numbers.  If a number is  bigger than  9999999999999999,  FoxCalc switch to
scientific  display  (eg. 09E-42).  The internal  FPU  resolution  is of 15
decimal  digits,  numbers are  rounded to  10 decimal  digits  before being
displayed. The range of supported numbers is from -10^50 to 10^50.

CODEPAGE
As there are some buttons which are described with ASCII characters greater
than ASCII #127,  FoxCalc is detecting the system's codepage and change the
buttons  descriptions if  the codepage  can't display  them  correctly. For
example, the square button is "" on CP437, and becomes "SQR" on CP850.
