Is the objection over the reference to PI() rather than directly using the
Greek letter Pi?
Or is the choice of convention the problem?
According to http://mathworld.wolfram.com/InverseCotangent.html there are
two conventions: (0,Pi) or (-Pi/2, Pi/2). The former is continuous, while
that later has a discontinuity at 0.
