# 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/](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`.
# BUGS
Please report any bugs or feature requests to
`bug-math-bigint-gmp at rt.cpan.org`, or through the web interface at
[https://rt.cpan.org/Ticket/Create.html?Queue=Math-BigInt-GMP](https://rt.cpan.org/Ticket/Create.html?Queue=Math-BigInt-GMP)
(requires login). We will be notified, and then you'll automatically be
notified of progress on your bug as I make changes.
# SUPPORT
After installing, you can find documentation for this module with the perldoc
command.
perldoc Math::BigInt::GMP
