Does CC use -Pi to Pi (or -2Pi to 2Pi) for radian measurements? Or does it use continuous scale from -inf to inf?
Right now, I've got a script that measures the angle of incidence and sees if a particle's heading is going within Pi/2 of a normal, but for some reason it does not work for angles going about Pi/3 from normal in the first quadrant.
Here's my detection script.

I thought it was -Pi to Pi, which is why I added math.pi to both sides to make both positive measurements.

It's 2pi is one full circle.

Yeah, but it goes negative. So does it loop over again (-2pi to 2pi) or is it continuous (-infpi to infpi)?

2pi is one full circle, -2pi is also one full circle.

But, when you reach -2pi, does it loop over again to 0, or does it continue on to -2.1pi, -2.5 pi, and so on?

EDIT: What I'm getting at here is, should I modulo my angles by 2pi before I test them or not.

I am fairly sure that it loops back to 0. Try printing on an object set to constantly rotate.

It goes from -pi to pi, yes. I'm too tired to think what's wrong with the code.

I did some more testing, and it looks like the problem is right around 0 rads. Any more than a few tenths of a rad more or less and it works fine. I'll see if I can fiddle with it some more.

EDIT: Fixed with adding 3/2pi instead of pi.
