Expression for decimals.

[RobertP]

I need to limit the characters after the decimal to 1 or 2. this is what i have.

 

^[0-9]+(?:\.[0-9]*)?$

 

I think i have to add {1,2}, but no idea where.

 

Any help would be greatly appreciated.

* means between 0-unlimited times.

 

You probably want that as {1,2}
