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. I may or may not add them in later, I couldn't get MSVC to compile MMX intrinsics.

WebThe atan ( 2 z) table can be split into multiple subtables that correspond to 0 ≤ z < 1 and different floor ( log 2 ( z)) with z ≥ 1, which is easy to calculate. The table lengths can be chosen as guided by Fig. 3. The within-subtable index can be calculated by a simple bit string manipulation. WebDescription. The atan2 (a,b) function computes four-quadrant inverse tangent of elements of two vectors. The elements of the output vector y are computed as the four-quadrant arctangent of a [i] / b [i]. The atan2 (a,b) function does not generate any errors.
