Don't think so. If you don't want to take care of non-numeric keys,
which is easy:
on keydown
if "0123456789." contains the key then pass
end
you could always let them type whatever they like, and then calculate
using the value() rather than the string. That way if they enter
alpha characters, it would evaluate to zero.
