header file to .h) and get it integrated into parrot.

I'm not really sure if types/bignum.c is what we want. There are AFAIK
some other math packages around, which are maintained and more complete.
GMP comes to my mind.

The only thing that worries me about GMP is the license. It's LGPL,
so we might be able to, but it's tough to tell for sure, and the
explanatory text doesn't help at all.
The only bignum stuff I want in the core is the
basics--extended-precision numbers and basic math. (If we get
transcendentals as a bonus, well... swell) I think I'd as soon just
flesh out what we have now and be done with it.

But on second reading it the license makes this untenable. If we did
use the GMP library and shipped it with parrot then we'd be obligated
to package the full GMP source code with every binary distribution,
so... no joy there.

Anyone working on that? Who volunteers?

I'll take a whack at it after I'm done with my exams if
noone beats me to it.

Good. I should probably have mentioned that bignums should be usable
tomorrow :) OSCON with pie throwing contest is coming ...

Then somebody should beat me to it unless Dan really, really
likes pies ;)

Mmmm, pie! But, like so many other things, best served rather than thrown.

There is now a BigNum PMC in CVS. It uses libgmp if present currently.
Other implementations are welcome.
