How about something like this?
/\d{0,3}\.\d{0,3}/
which should match 0-3 digits followed by a period followed by 0-3 digits.
You should be able to see how you can change it if you want to expand how
many digits to capture. You could also try:
/\d+\.\d+/
Which matches one or more digits followed by a period followed by one or
more digits. This will fail, though, on a number like this: .10 or 1., so
it depends on what you want to allow as far as the user entering data.
