Regular Expression to accept all the decimals from 0 to 100
===

I want to modify my existing Regular Expression which accepts decimals from 0 to 99.99

    \d{0,2}(\.\d{1,2})?$ 

i want this to be **accept**

    100
    100.0
    100.00

and should **not accept**

    100.1
    100.02
    101

Can anyone help me modify the above RE
