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.
