Synopsis
_mm_atan2_ps(__m128 a, __m128 b);
Description
Compute the inverse tangent of packed single-precision (32-bit) floating-point elements in "a" divided by packed elements in "b", and store the results in "dst" expressed in radians.
Operation
FOR j := 0 to 3
i := j*32
dst[i+31:i] := ATAN2(a[i+31:i], b[i+31:i])
ENDFOR
dst[MAX:128] := 0
