Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num attributes
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);
This provides a simple numeric attribute, which supports most of the basic math operations.
It is important to note that all those methods do in place modification of the value stored in the attribute. These methods are implemented within this package.
Alternate way to set the value.
Adds the current value of the attribute to $value.
$value
Subtracts $value from the current value of the attribute.
Multiplies the current value of the attribute by $value.
Divides the current value of the attribute by $value.
Returns the current value of the attribute modulo $value.
Sets the current value of the attribute to its absolute value.
