better than double

[Poincare]

I want to make a program that calculates pi. The thing is that having only so few digits with double doesn't satisfy me. I want more digits. I know I only have a 32 bit processor so i can't go more than 4294967296 with just one variable. But, wanted to make some kind of a variable that can handle as many digits as possible until my processor maxes out.

Someone told me this was doable with assembly but I really want to steer clear of assembly since i'm a novice.

You may or may not have a long double type that is bigger than double. But even that probably won't suit your desires; in which case you can either write your own multiple-precision library or use someone else's.

Is there an open source library that does that?
