Any thoughts on how to relatively easily define quadrants in a circle around
a point? I¹d like to ID the area between 315-45 degrees (N quadrant), 45-135
degrees (E quadrant), 135-225 (S quadrant), and 225-315 (W quadrant). I¹ve
come up with a couple of complicated ways and wonder if I¹m missing an
easier one?
