#SYNOPSIS

package Real;

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.
