bigger int containers in c++

[tecknophreak]

the largest integer i can use it the long long int. but that only gives me 18 good digits. i want something like oh, 50 or 100. :( i need all digits so i can't use double or float. i'm doing some encryption and prime searching, so i need these large numbers.

:cool: bignums :cool:

I believe the GNU bignums library is called gmp, but I'm not sure on that one. Go look at their FTP site for gmp, if it isn't there, somebody else might know what it's called.

Yeah, gmp.
