大整数的四则运算算法 用vc.net2003编写，稍微修改就可以在vc6.0运行

BigInteger for c# with pretty realization : number stored not as BCD, but as it s byte-representation

大整数库，实现了大整数之间的四则运算和模、模幂运算以及最大公约数的求解-Large integer library to achieve a large integer arithmetic and between modes, modular exponentiation and the greatest common divisor of the solution
