Float Numerical Field Validate

I have a textfield that user can enter only numbers.

How i can validate the field that when the number is float, it can have max 2 pre decimal and 2 decimal numbers?

Not sure if I understood your question, here is numerical validator document.


If it cannot solve your issue, you may look for extension for validation, then base on this code you can do a little change to create one by yourself.

For example:


try this

array('percent', 'numerical', 'allowEmpty' => true,

                                'integerOnly' => false, 'min' => 0, 'max' => 100),

Thank you all for your replies.

I use the one Maggie suggested and then with numberPattern option i use a regular expression to filter the format I want.

Thanks for your time and suggestions!
