# Math::GSL::PowInt(3pm)

Integer Power functions

## NAME

Math::GSL::PowInt - Integer Power functions

## SYNOPSIS

```
    use Math::GSL::PowInt qw /gsl_pow_2 gsl_pow_4 gsl_pow_int/;
    print '2**4  = ' . gsl_pow_2(4) . "\n";
    print '4**7  = ' . gsl_pow_4(7) . "\n";
    print '17**5 = ' . gsl_pow_int(17,5) . "\n";
```

## DESCRIPTION

This module implements the GSL Integer Power functions, which allow one to quickly compute a given integer raised to any real number.  It contains gsl\_pow\_2 to gsl\_pow\_9 and gsl\_pow\_int. If you need a power higher than 9, you can use gsl\_pow\_int, which takes a base as the first argument and power being raised to as the second argument.

You can also write

`"use Math::GSL::PowInt qw/:all/;"`

to use all available functions of the module.

## PURPOSE

This module doesn't provide much performance improvement over the Perl builtin '\*\*' operator, but is included for completeness.
