I am in need of 2 regular expressions, one that will validate a minimum of 2 decimal places ie: 1283772.23, just must enter 2 decimal places.

The other that I need is one that validates a time for a race, example: 04:03.4

Any help would be appreciated, thanks !!

    First one ^\d+(\.\d{1,2})?$ Second one ^\d{1,2}:[0-5]\d\.\d$

    The first one doesnt appear to force 2 decimal places, I can enter just 1 and it passes? I havent tested the second one yet...

    This will allow any number of decimal places as long as you have at least 2
    ^\d+\.\d{2,}$

    This one will allow 2 decimal places only
    ^\d+\.\d\d$
