NAME

Geometry::Formula - methods to calculate common geometry formulas.

VERSION

Version 0.01

SYNOPSIS

use Geometry::Formula

my $x = Geometry::Formula->new;

DESCRIPTION

This package provides users with the ability to calculate simple geometric problems using the most common geometry formulas. This module was primarily written for education and practical purposes.

CONSTRUCTOR

new(): Returns a reference to a new formula object. No arguments currently needed or required.

SUBROUTINES/METHODS

The following methods are used to calculate our geometry formulas. Keep in mind each formula has a unique set of constructors/parameters that are used and must be provided accordingly. All attempts have been made to prevent a user from providing invalid data to the method.

Methods are named after the 2d and 3d shapes one would expect to find while using geometric formulas such as square or cube. Please see the individual method items for the specific parameters one must use. In the example below you can see how we make usage of Geometry::Formula:

use Geometry::Formula;

my $x   = Geometry::Formula->new;
my $sqr = $x->square{ formula => 'area', side => 5 };

print $sqr;

HELPER SUBROUTINES/METHODS

While documented typically you will not call these methods directly. These methods are provided for readability and parameter validation.

$self->_squared( int ): numeric values passed to this function get $self->_squared and returned.
<$self-_cubed( int ) >>: numeric values passed to this fucntion get$self->_cubed and returned
_param_check( $name_of_method, %param ): this method validates the parameters being passed into our formula methods are properly constructed.

DIAGNOSTICS

N/A at the current point in time

CONFIGURATION AND ENVIRONMENT

This package has only been tested in a 64bit Unix (OSX) environment however it does not make usage of any code or modules considered OS specific and no special configuration or configuration files are needed.

INCOMPATIBILITIES

This package is intended to be compatible with Perl 5.008 and beyond.

BUGS AND LIMITATIONS

The package cannot prevent users from specifying duplicate keys within a method. When validating parameters the first error that is caught will be reported even in the event that additional errors exist. The methods provided were not intended to handle very large numbers.

DEPENDENCIES

No modules outside of the perl core/base install.

SUPPORT

The module is provided free of support however feel free to contact the author or current maintainer with questions, bug reports, and patches.

Consideration will be taken when making changes to the API. Any changes to its interface will go through at the least one deprecation cycle.
