Please wrap code it <code> tags to keep things legible. As you can see, your character classes got linkified.

1234 is passing because it's being read as (123)(4). You should set the whole part following and including the decimal in a non-capturing group with a conditional: /^[-+]?[0-9]{0,3}(?:\.[0-9]{0,3})?%?$/ I've also removed a bunch of unnecessary escaping, and changed your {0,1} to the shorter ? synonym.

A read through of perlretut may be helpful.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
