bignum library - test1.cpp - calculate 1000 factorial

//a bignum library written in C++, it can (in theory) calculate with 4 billion digit long numbers
//this is mostly for demonstration purposes, if you need performance, use something like GNU arbitrary precision library
//Implemented by: http://www.youtube.com/user/thecplusplusguy
//this might be an older version, I have to check
//calculate 1000 factorial
#include <iostream>
#include "bignum.h"

int main()
{
    bignum fact=1;
    for(int i=1;i<=1000;i++)
        fact*=i;
    std::cout << fact << std::endl;
