The atan2 function follows the convention that atan2(x,x) returns 0 when x is mathematically zero (either 0 or -0). …
In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, $${\displaystyle \theta =\operatorname {atan2} (y,x)}$$ is the angle measure (in radians, with $${\displaystyle -\pi <\theta \leq \pi }$$) between the positive $${\displaystyle x}$$-axis and the ray from the origin to the point See more The ordinary single-argument arctangent function only returns angle measures in the interval $${\displaystyle {\left[-{\tfrac {1}{2}}\pi ,+{\tfrac {1}{2}}\pi \right]},}$$ and when invoking it to find the angle measure between the x-axis … See more As the function atan2 is a function of two variables, it has two partial derivatives. At points where these derivatives exist, atan2 is, except for a constant, equal to arctan(y/x). Hence for x > 0 or y ≠ 0, Thus the See more The $${\displaystyle \mathrm {atan2} }$$ function was originally designed for the convention in pure mathematics that can be termed east-counterclockwise.
