WebJun 20, 2024 · atan2 () is an inbuilt method in Java that is used to return the theta component from the polar coordinate. The atan2 () method returns a numeric value between – and representing the angle of a (x, y) point and the positive x-axis. It is the counterclockwise angle, measured in radian, between the positive X-axis, and the point …
WebI recently implemented tan, cot, atan, atan2 using SSE2 intrinsics, which serve as extensions to the SSE2 implementations of sin, cos, exp, log by Julien Pommier. WIP because the original library also implements SSE1 + MMX, which mine don't.
