well, people have mentioned ruby has a fast version of those. i would
imagine its license is compatible with perl but IANAL (hey, i used that
for the first time since i learned it at the first perl quiz show and
didn't know it).
not that it would help much, but many eons ago i wrote a packed decimal
math library for PL/I. i was taught a trick (excess 3) where you use 32
bit integer math and shifts to do adds very quickly. everything else sat
on top of add. :). i would imagine bigint would be similar in some ways.
regarding bigfloat, i can see both the mantissa and the exponent
growing. i seem to get from this thread that the exponent does has a max
value of some large int (32 bits?). is this a reasonable limitation? it
does seem kinda large having a max exponent in the billions. :)
