_mm_atan_ps
,
_mm256_atan_ps

Calculates inverse tangent value. Vector variant of atan(x) function for a 128-bit/256-bit vector argument of float32 values.

Syntax

extern __m128 _mm_atan_ps(__m128 v1);
extern __m256 _mm256_atan_ps(__m256 v1);
Arguments
v1
vector with float32 values
Description
Calculates the arc tangent of vector
v1
elements. In effect, the tangent of each resulting element value is the value of the corresponding
v1
vector element.
Returns
128-bit/256-bit vector with result of the operation.
Many routines in the
svml
library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
