## Simple big rational calculator

The simplest big rational calculator is available for DOS and MS-Windows.
The calculator is very simple
and I think it does not need manual. Try these:

-2/3+1/6+6/5;
25 div 4;
25 mod 4;
100!;
100^100;
((((1+2)*3-4)/5-6)*7+8)/9-10;
32!/10!^3/2!;

(Don't forget semicolon at the end of each expression)

You can try also `10000!;` and compare the time required with one required
for the computation of 10000 factorial in Maple (c) or in Matlab (c) or in your
other preferable mathematical package.

You can download binaries:

The program is written on the base of my unlimited-precision
arithmetic library (C++).
