I have a 1000×1000 grid with a fixed point (p1) in the centre and a variable point (p2). How can I calculate, in degrees, the angle indicated in red? The vertical blue line will always be fixed as 0 degrees.
Many thanks in advance.

arctan(p2.y/p2.x) + 90works for the upper-left quadrant. Depending on how you want to calculate the other quadrants you can either use the same formula or use the inverse asabs(result - 180)
