Hi! Just giving you feedback. Your regexp not only pass numbers but every string containing at least one number.
Take a look at the
^and$reserved chars for regexp and think about the floating point your system is using.Something like
^[\d]+$for only integers.Anyway, you can use isNaN and it's probably a better approach.
