NAME

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

VERSION

       version 2.1005

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.

       •   add($value)

           Adds the current value of the attribute to $value.

       •   sub($value)

           Subtracts $value from the current value of the attribute.

       •   mul($value)

           Multiplies the current value of the attribute by $value.

       •   div($value)

           Divides the current value of the attribute by $value.

       •   mod($value)

           Returns the current value of the attribute modulo $value.

       •   abs

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