iphone - What is the best way to enter numeric values with decimal points?

Question

In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols.

Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final result?

Thanks!

I think it would be good to point out that as of iOS 4.1 you can use the new UIKeyboardTypeDecimalPad.

So now you just have to:

myTextField.keyboardType=UIKeyboardTypeDecimalPad;
