How to I control what can be entered into specific field types?

I'm trying to control a field type so that only numeric characters (no alpha, punctuation, or spaces) can be entered.

I have looked into controlling field behaviour many times, and read through the different field types but have not been able to find what I need.

Is there some sort of qualifier I can set? Or is there a plug-in that adds a "number only" field option?

Any suggestions or directions would be much appreciated!

There's a simple "number" custom field type - if you use that, the users won't be able to commit anything other than numbers.

You could also find/write a plugin (or use the script runner) to provide a validator that can check the input as well, if the simple number field isn't clever enough for you.
