Rose::HTML::Form::Field::Numeric is a subclass of Rose::HTML::Form::Field::Text that only accepts numeric values. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid number, or setting an error message and returning false otherwise.
Use the min and :<max|/max> attributes to control whether the range of valid values.
Get or set the maximum acceptable value. If the field's internal_value() is greater than this value, then the validate() method will return false. If undefined, then no limit on the maximum value is enforced.
Get or set the minimum acceptable value. If the field's internal_value() is less than this value, then the validate() method will return false. If undefined, then no limit on the minimum value is enforced.
If BOOL is true or omitted, sets max to 0. If BOOL is false, sets max to undef.
0
If BOOL is true or omitted, sets min to 0. If BOOL is false, sets min to undef.
