2). How do you handle numbers that large, while maintaining
precision. keep them as strings - and/or use a 64bit machine?
a 64bit machine would make the number larger, not unlimited :) Even GMP (or BC) isn't unlimited... It's just limited to the number of bytes you have in RAM/swap. :-)

Yeah, well if you have a few TB of space, which you set up as swap, the number would come really close to unlimited :) But of course it is limited :P So if you have 10 TB of swap(I believe current kernels can't handle that, but that's another story) you could get a number as big as 2^87960930222081 Tell me any example where you would use a number larger than that :) Tijnema
