I'm working on a project that requires: - arbitrary size integer arithmetics - extraction of logarithms with a good precision \ fixed point arithmetic - " square roots /
IEEE 80-bit arithmetic isn't suitable ; in fact, it gives artifacts as some large numbers (> 20 decimal digits) are computed and rounded to fit in the 64-bit mantissa.
Several libraries (such as GMP) exist for the first part ; but the tricky parts are the second and third. The PARI package does that ; but it's interface and overall design is clunky ; besides, it's not that fast.
Do you know of any package, easily interfacable with C or Perl, that does the said work?
Please answer by e-mail to email@example.com . Thanks!
