Simple regular expression!

I want to use regular expression to test if a price (decimal) has the correct format:

Now I�m allowed to type in a positive integer with 2 decimals, i.e. 15.50.

Script:
document.form1.productPrice.value.match(/^\d+(\.\d{2})?$/)

I also want to be able to type in a positive integer with 1 decimal only!

Have can I do that?
