ArcTan2
The function $\operatorname{atan2}(y,x)$ (from "2-argument arctangent") is defined as the angle in the Euclidean plane, given in radians, between the positive x-axis and the ray to the point $(x,y)$.
$\operatorname{atan2}(y,x)$ returns a single value $\theta$ such that $-\pi < \theta \le \pi$ and, for some $r > 0$,
