55 | =head1 DESCRIPTION |
56 | |
7795e4de |
57 | This trait provides native delegation methods for numbers. All of the |
58 | operations correspond to arithmetic operations like addition or |
59 | multiplication. |
60 | |
61 | =head1 DEFAULT TYPE |
62 | |
63 | If you don't provide an C<isa> value for your attribute, it will default to |
64 | C<Num>. |

66 | =head1 PROVIDED METHODS |
67 | |
7795e4de |
68 | All of these methods modify the attribute's value in place. All methods return |
69 | the new value. |

e132fd56 |
85 | =item * B<div($value)> |
e3c07b19 |
