Variable-precision arithmetic

[RedSon]

Every now and then I have a need to compute arbitrarily large numbers. Can anyone recommend a good (free) library in any language that is worth taking a look at?

It'd be nice to have a list for most popular languages, like Java has BigInt and other Big* classes but I'd like to know if other languages have similar products.

This wiki page mentions quite a few libraries for bignum functionality.

kind regards,
