[RESOLVED] how to validate decimal number input

[ssffcc]

hi, I have a input field "Milage", which might be either integer or decimal numbers, please help me validate the input

[schizo]

I usually use the is_numeric (http://www.php.net/manual/en/function.is-numeric.php) method to help validate this type of input.
