I know this is probably a pretty stupid question, but I'm a programmer and I'm trying to describe a function which does a math calculation in a mathematical format. Stripped of all but the relevant portion, this is what I'm trying to describe:

Is there a mathematical symbol or set of symbols used to represent that? Thanks and sorry for bothering you with such a simple question. (I don't know how to phrase this as a good Google search)Code:if (x-y) < 0 then 0 else (x-y)
