Remove Comma, show decimals 1

[wsproperties]

I have the following formula
totext(Sum ({@giftamt}, {gifts.giftacctno}),0,"") It returns a number similar to this: $8720. Thus I successfully removed the comma. However I want to remove the dollar sign and add two decimals at the end. Thus $8720 becomes 8720.00. How would I accomplish this?

totext(tonumber(Sum({@giftamt},{gifts.giftacctno})),2,"")
