Re: Re: integer validation

That allows the following input:

-54
54-
5-4

I try to specify exactly what is valid:

/^-?\d+$/

Update: Yup, Kanji is right (note the lowercase z). I never had that problem because I chomp my input first.

I try to specify exactly what is valid: Then wouldn't you want `/\A-?\d+\z/`? If it's there, `$` will match a single newline at the end of your string, and you'd end up matching something bogus like "7\n". --k.	[reply]
