NAME
       Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num
       attributes

VERSION
       version 2.4000

SYNOPSIS
         package Real;
         use Moose;

         has 'integer' => (
             traits  => ['Number'],
             is      => 'ro',
             isa     => 'Num',
             default => 5,
             handles => {
                 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);

DESCRIPTION
       This trait provides native delegation methods for numbers. All of the
       operations correspond to arithmetic operations like addition or
       multiplication.

DEFAULT TYPE
       If you don't provide an "isa" value for your attribute, it will default
       to "Num".

PROVIDED METHODS
       All of these methods modify the attribute's value in place. All methods
       return the new value.

       o   add($value)

           Adds the current value of the attribute to $value.

       o   sub($value)

           Subtracts $value from the current value of the attribute.

       o   mul($value)

           Multiplies the current value of the attribute by $value.

       o   div($value)

           Divides the current value of the attribute by $value.

       o   mod($value)

           Returns the current value of the attribute modulo $value.

       o   abs

           Sets the current value of the attribute to its absolute value.

BUGS
       See "BUGS" in Moose for details on reporting bugs.
