=head1 NAME

DBIx::Class::Helper::Row::NumifyGet - Force numeric "context" on numeric columns

=head1 SYNOPSIS

 package MyApp::Schema::Result::Foo_Bar;

 __PACKAGE__->load_components(qw{Helper::Row::NumifyGet Core});

 __PACKAGE__->table('Foo');
 __PACKAGE__->add_columns(
    foo => {
       data_type         => 'integer',
       is_nullable       => 0,
       is_numeric        => 1,
    },
 );

 sub TO_JSON {
    return {
       foo => $self->foo,  # this becomes 0 instead of "0" due to context
    }
 }

=head1 METHODS

=head2 get_column

This is the method that "converts" the values.  It just checks for
C<is_numeric> and if that is true it will numify the value.

=head2 get_columns

This method also "converts" values, but this one is called a lot more rarely.
Again, It just checks for C<is_numeric> and if that is true it will numify the
value.
