How can I validate number between 1 and 99 using regular expression? [closed]

Answer 1

A simple version is ^[1-9][0-9]?$ for integers and ^([1-8][0-9]?|9[0-8]?)\.\d+$ for floats. If you want one for both: ^(([1-8][0-9]?|9[0-8]?)\.\d+|[1-9][0-9]?)$

Test it here

Answer 2

Try [1-9][0-9]?(.[0-9]*)?

Edit: The above include 99.something too. This shouldn't:

[1-9](([0-8](\.[0-9]*)?)|[0-9])?

Test it here, it works. ;)
