Vector Length's don't repeat, but Angular components repeat themselves modulo 2 PI or 360 degrees so when I saw the label "Mod" I was confused thinking it might represent the angular component of the polar coordinate pair. Anyway "Mod" and "Arg" don't give any clue as to weather they represent length or angular properties, that is why I suggested "Range" and "Angle" which clearly do. Out of the three choices above, I prefer "Range" and "Angle". As you say, they are descriptive and unambiguous. I chose "Mod" and "Arg"  short for modulus and argument  because that's what I've always called these two properties of a complex number; I think they are standard mathematical terms. I'm quite happy to change, though. Nigel (UK)
