=head1 NAME
Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num attributes
=head1 VERSION
version 2.4000
=head1 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);
=head1 DESCRIPTION
This trait provides native delegation methods for numbers. 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.
