FOXCALC is a simple calculator for DOS with a text user interface. The program has a mouse suport, so take care to run your mouse driver before launching FOXCALC; it will be much easier to use it.

If you really can't use a mouse, you will find below the list of shortcut keys. That list should automatically appear anyway if FoxCalc can't find a mouse driver. Key Function 0-9 0-9 (numbers) "+" + (addition) "-" - (subtraction) "=" or ENTER = (return) "." . (comma) "*" * (multiplication) "/" / (division) "%" % (percent) "]" (square root) "[" (square) "^" (exponentiation) "!" x! (factorisation) ":" MOD (modulo) "m" M+ (memory addition) "M" M- (memory subtraction) "r" MR (memory Recall) "c" MC (memory Clear) "\" +/- (change signum) ESC OFF (exit) DEL AC (clear all) BackSpace C (clear) "s" snd (sound on/off) "?" ? (about the program)

CALCULATION FoxCalc makes use of the GMP (Gnu Multi-Precision) library and the MPFR library for all calculations. This makes it an accurate and very reliable tool. All operations are performed with a precision of 60 digits. Floating point numbers which don't fit into the window are truncated without any rounding. When using the MOD function in FoxCalc, you can get different results than in other computer calculators or programming languages. That's not a bug. The modulo operation on negative numbers can be done using several methods. Usually, computers process an "X MOD Y" operation using absolute values of X and Y, and change the result's sign to the X's sign. That's the easiest way, and that's how Intel processors work. FoxCalc behaves differently. Therefore, the "7 mod -3" operation may be computed as "1" on other calculators, while FoxCalc will report "-2" Both results are correct. CODEPAGE & LOCALES: As there are some buttons which are described with ASCII characters greater than ASCII #127, FoxCalc detects the system's codepage and changes the buttons descriptions if the codepage can't display them correctly. For example, the square button is "û" on CP437, and "SQR" on CP850. The separators (decimal separator and thousands separator) are copied from the system's settings. If you would like to change them, just change your system's settings (usually using COUNTRY.SYS).
