limiting decimal places in a formula field

limiting decimal places in a formula field

I have a formula field that calculates a percent. I'd like to limit the result that is displayed to two decimal places, but can't figure out how to go about this. Using decimalplace=2 (as shown here https://www.zoho.com/creator/help/script/expressions.html) doesn't seem to work. Is there another approach that will keep me from getting insanely long numbers like .2398759845?
