NAME

            

              
              
Math::Fortran - Perl implementations of Fortran's sign() and log10()
            
          

SYNOPSIS

            

              
              
use Math::Fortran qw(log10 sign);
$v = log10($x);
$v = sign($y);
$v = sign($x, $y);
            
          

DESCRIPTION

This module provides and exports some mathematical functions which are built in in Fortran but not in Perl. Currently there are only 2 included.

FUNCTIONS

log10()

Log to the base of 10

sign()

With 1 parameter, +1 if $y >= 0, -1 otherwise. With 2 parameters +abs($x) if $y >= 0, -abs($x) otherwise.

BUGS

I welcome other entries for this module and bug reports.
