From what I checked, it seems that it may depend on browser. With following pattern, Chrome allows numbers only, Firefox marks numbers with coma or dot as invalid and IE allows [a-z] as well.

^([1-9]|\.|\,)+([0-9])*(\.|\,)?([0-9])*$

I would add onchange event and set it up with javascript, because I can't see pattern, which will allow/disallow 0 based on first character and will remove browsers differences. 0,1 is still number.
