NAME
Math::GSL::PowInt  Integer Power functions
CONTENTS
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 avaible functions of the module.
PURPOSE
This module is used to speed up arithmetic operations. The underlying code
decomposes the multiplication in the most efficient way. Since it is
implemented in XS (via SWIG), it should lend a large performance increase over
the Perl builtin exponentiation operator, ’**’ .
