Always display decimal?

I am working on a platformer with a pretty unique level in which the player has to gather money to perform any and all actions, such as walking or jumping. I have a display set up to show how much money the player has at any given moment, and for aesthetic purposes, I want it to display the usual money format of something like $1.00. It'll do it when you have something like $2.45, but will shave off decimals that aren't strictly necessary. Is there any way to force clickteam to always treat a value like a float? Or simply get it to display that value that way? Right now I am reading an objects alterable value into a string.
