Answer: A. Nice one all.

Can anybody help me out here and has a use case for using the Sign node rather than LT 0 and/or LE 0 to identify the sign of a double. I my mind this node should be called something like Change Magnitude to 1.

I think I have only used this function in conjunction with a Subtract in order to figure out if X was >, <, or = to Y. It was easier than doing all of the logic and manipulating that somehow to use with a case structure.
