Hello friends,
I want regular expression for validating input between -100 to 100 only

Input like 99.99 and -99.99 and 0 too

Currently i used :

C#

Above reg-ex will allow 0 to 100 decimal up to 2 digit.

ehm, how did you create that regex above? And why do you not see how to add the '-' at first position?

With 2 digits, it's not -100 to 100, it's -99 to -99. The solution: allow 1 to 2 digits and, before digits, 0 to 1 '-'.
