math question dealing with money (decimals)

[csphard]

I have 2 fields in my table
quantity int(11)
price decimal(3,2)

In my php I perform the following arithmetic

($price * $qty)


9.00 * 1 it returns 9 but I want this to be 9.00
9.00 * 2 it returns 18 but I want this to be 18.00

What do I have to do to get the cents to display if it is 00.

I found my answer:

number_format(($price * $qty),2)
