Best ResponseYou've already chosen the best response.1In mathematics, the sign function or signum function (from signum, Latin for "sign") is an odd mathematical function that extracts the sign of a real number. In mathematical expressions the sign function is often represented as sgn.

Best ResponseYou've already chosen the best response.1Maybe I have seen it before but just don't remember too well. I don't think this is my first time seeing it. Just been a while and I don't think we went over sgn function in any detail at all.
