How to allow only three numbers before a decimal point and two numbers after it. Is there a regex for this?

Only numbers between 0.00 and 100.00 can be allowed. The number can also be without decimal point. I am trying to use this regex,

/^[1-9][0-9]{0,2}(?:,?[0-9]{3}){0,3}(?:\.[0-9]{1,2})?$/

But this allows more than 3 numbers before decimal point. Trying to use the regex in ng-pattern of angular js.

Try `/^(?:\d{1,2}(?:\.\d{1,2})?|100(?:\.0{1,2})?)$/`, see https://regex101.com/r/wanOHb/1 – Wiktor Stribiżew Feb 28 '19 at 11:37
I've resolved this by using min(set to 0) max(set to 100) of angular and little change in regex - /^[0-9]{0,2}(?:,?[0-9]{3}){0,3}(?:\.[0-9]{1,2})?$/ – user2867091 Mar 05 '19 at 07:39
