- (* arctan2 returns the angle (in radians) with tangent A/B
- arctan2(A,B)=arctan(A/B)
-
- Also, arctan2 returns a value in the range 0 to 2*pi
- Whereas arctan returns the value in the range -pi/2..pi/2
-
- This means that arctan2 can be used directly for rectangular
- to polar co-ordinates. In addition, arctan2 works when B=0.0*)

- END MathLib0.
