I need big integer library.

Hello all programmers.

I need use very big integer (128, 256 and more bit length) in my
program. Do anyone known where is free (or not free) library for
support this integer?

Many thanks.

Mike.

Have you tried googling for it? Search for 'bigint', or, if you're
so inclined, "arbitrary precision integer arithmetic C++".
