Atan2

In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, θ = atan2 ⁡ ( y , x ) {\displaystyle \theta =\operatorname {atan2} (y,x)} is the angle measure (in radians, with − π < θ ≤ π {\displaystyle -\pi <\theta \leq \pi } ) between the positive x {\displaystyle x} -axis and the ray from the origin to the point ( x , y…
