=head1 NAME
Math::BigInt::GMP - backend library for Math::BigInt etc. based on GMP
=head1 SYNOPSIS
# to use it with Math::BigInt
use Math::BigInt lib => 'GMP';
# to use it with Math::BigFloat
use Math::BigFloat lib => 'GMP';
# to use it with Math::BigRat
use Math::BigRat lib => 'GMP';
=head1 DESCRIPTION
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 L<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.
