The return value is the number of radians clockwise from the 12 o'clock direction,

Taking this point to be the centre of a circle, and the other point being a position on
the circumference, the return value is the number of radians clockwise from the 12 o'clock
direction.
So 12 o'clock = 0, 3 o'clock = Pi/2, 6 o'clock = Pi, 9 o'clock = -Pi/2
