=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.

=head1 BUGS

Please report any bugs or feature requests to
C<bug-math-bigint-gmp at rt.cpan.org>, or through the web interface at
L<https://rt.cpan.org/Ticket/Create.html?Queue=Math-BigInt-GMP>
