Non-arbitrary integer math

[mykroft]

Hi all,

I've been searching for math libraries that define non-arbitrary
length integer types. Including but not limited to signed/unsigned
1/2/4/8/16 byte types.

I've tried searching "the vaults" and previous c.l.p posts, without
much success. The struct and array module's won't do either.

Most of the math I need to do is integer arithmetic. For now I'm
coding my own version of these but if this has been done before, Id
rather not repeat it.

Thanks,
mykroft
