I am looking to build 2 regex with those constraints :
- 0 to 100
- 2 decimals places (like 15.25 or 0.01)
- But 100.01 is not acceptable
- No negative number
For the second regex, I need it to go up to 200 instead of 100 but same for the rest.
Currently, I have this one for 0 to 100 :
^([0-9]|[1-9][0-9]|100)?$
and this one for 200
^([01]?[0-9][0-9]?|200)?$
I can get 0 to 100 or 200 numbers but without decimal places.

First regex: /^([0-9]{1,2}|[0-9]{1,2}\.[0-9]{2}|100)?$/

You can extend your regex like this:
^([0-9]|[1-9][0-9]|(?:[0-9]|[1-9][0-9])\.(?:[0-9]|[0-9][0-9])|100)?$
You can try it here: https://regex101.com/r/HBidWk/1
This is for 0-100
