  package Real;
  use Moose;
  use MooseX::AttributeHelpers;

  has 'integer' => (
      metaclass => 'Number',
      is        => 'ro',
      isa       => 'Int',
      default   => sub { 5 },
      provides  => {
          set => 'set',
          add => 'add',
          sub => 'sub',
          mul => 'mul',
          div => 'div',
          mod => 'mod',
          abs => 'abs',
      }
  );

  my $real = Real->new();
  $real->add(5); # same as $real->integer($real->integer + 5);
  $real->sub(2); # same as $real->integer($real->integer - 2);

This provides a simple numeric attribute, which supports most of the basic math operations.

All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
