61 basic math operations.
63 =head1 PROVIDED METHODS
65 These methods are implemented in
66 L<Moose::Meta::Attribute::Native::MethodProvider::Bool>. It is important to
67 note that all those methods do in place modification of the value stored in
74 Sets the value to C<1>.
78 Set the value to C<0>.
82 Toggles the value. If it's true, set to false, and vice versa.
86 Equivalent of 'not C<$value>'.
