I consider this a very strange definition of "correct". The point (pun
intended) of floats is precisely to be able to have a decimal point. It
is absolutely ridiculous to filter that out by default. Do you have to
explicitly allow "@" when filtering e-mail addresses?
From the manual:

^^^^^^^^^^^^^^^^
I would consider that appropriate when filtering for numbers in general,
but certainly not when explicitly dealing with floats. Is there a
rationale for this WTF?
