All of the operations correspond to arithmetic operations like addition or multiplication. =head1 DEFAULT TYPE If you don't provide an C<isa> value for your attribute, it will default to C<Num>. =head1 PROVIDED METHODS All of these methods modify the attribute's value in place. All methods return the new value. =over 4 =item * B<add($value)> Adds the current value of the attribute to C<$value>. =item * B<sub($value)> Subtracts C<$value> from the current value of the attribute. =item * B<mul($value)> Multiplies the current value of the attribute by C<$value>. =item * B<div($value)> Divides the current value of the attribute by C<$value>. =item * B<mod($value)> Returns the current value of the attribute modulo C<$value>. =item * B<abs> Sets the current value of the attribute to its absolute value. =back =head1 BUGS See L<Moose/BUGS> for details on reporting bugs. =head1 AUTHORS =over 4 =item * Stevan Little <stevan.little@iinteractive.com> =item * Dave Rolsky <autarch@urth.org> =item * Jesse Luehrs <doy@tozt.net> =item * Shawn M Moore <code@sartak.org> =item * יובל קוג'מן (Yuval Kogman) <nothingmuch@woobling.org> =item * Karen Etheridge <ether@cpan.org> =item * Florian Ragwitz <rafl@debian.org> =item * Hans Dieter Pearcey <hdp@weftsoar.net> =item * Chris Prather <chris@prather.org> =item * Matt S Trout <mst@shadowcat.co.uk> =back =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2006 by Infinity Interactive, Inc..
