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.
