I need help with a regular expression.
I need to make a decimal required up to 2 places.

Matches:
0.0
0.00

Not matches:
.0
0
0.000

Can anyone help?

\d\.\d{1,2}

?

That matches 0.000 aswell I think.

By matches, I mean it will match on the 5.63 in 5.637.

\d\.\d{1,2}$

The dollar indicates end of string, so should (in my head) match 1 or 2DP.
