backend library for Math::BigInt based on GMP
Math::BigInt::GMP is a backend library for Math::BigInt, Math::BigFloat, Math::BigRat and related modules. Math::BigInt::GMP provides support for big integer calculations by means of the GMP C library. See <https://gmplib.org/> for more information about the GMP library. Math::BigInt::GMP no longer uses Math::GMP, but provides its own XS layer to access the GMP C library. This cuts out another (Perl subroutine) layer and also reduces the memory footprint. Math::BigInt::GMP inherits from Math::BigInt::Lib.
