Math::NumberCruncher 5.00

Math::NumberCruncher Perl module contains a collection of useful math-related functions.

SYNOPSIS

It should be noted that as of v4.0, there is now an OO interface to Math::NumberCruncher. For backwards compatibility, however, the previous, functional style will always be supported.

# OO Style

use Math::NumberCruncher;

$ref = Math::NumberCruncher->new();

# From this point on, all of the subroutines shown below will be available # through $ref (i.e., ( $high,$low ) = $ref->Range( @array )). For the sake # of brevity, consult the functional documentation (below) for the use # of specific functions.
