# Math::BigInt::GMP(3pm)

backend library for Math::BigInt etc. based on GMP

## 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`.

## 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\> (requires login). We will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
