NAME
Math::BigInt::GMP - backend library for Math::BigInt etc. based on GMP
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';
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 <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.
STATIC FUNCTIONS
$str = gmp_version();
Returns the underlying GMP library's version as a string, e.g., 6.2.1.
