Not really. If someone says, "Turn 0 degrees from point A", you don't go anywhere. If, however, they say, "Turn 360 degrees from point A", you turn a full circle.

Just because 360 isn't on the list, doesn't mean that 0 has taken it's place.

I'm trying not to think of this in terms of pi. Stupid A-level Maths, making everything silly.
