Binary package “libmath-gmp-perl” in ubuntu mantic
high speed arbitrary size integer math for perl
Math::GMP was designed to be a drop-in replacement both for
Math::BigInt and for regular integer arithmetic. Unlike BigInt,
though, Math::GMP uses the GNU gmp library for all of its
calculations, as opposed to straight Perl functions. This can result
in speed improvements.
.
The downside is that this module is not 100% compatible to Math::BigInt.
