This class extends CNumberValidator so you can use all the options available there.
Additional option is replaceComma (default true) - this indicates whether the comma in attribute value should be replaced with dot.
Thanks to this you can validate your numeric fields with decimal comma (15,45 instead of 15.45) without filtering them first.
Remember that if replaceComma is set to false the attribute will not be changed so you have to prepare your database column properly.
Usage:
Import this class to your Yii application and use just like CNumberValidator. For example:
public function rules()
{
return array(
array('price', 'DecimalCommaNumberValidator', 'min' => 0),
);
}
