_mm_sincos_ps
,
_mm256_sincos_ps

Calculates the sine and cosine values. Vector variant of sincos(x, &sin_x, &cos_x) function for a 128-bit/256-bit vector with float32 values.

Syntax

extern __m128 _mm_sincos_ps(__m128 *p_cos, __m128 v1);
extern __m256 _mm256_sincos_ps(__m256 *p_cos, __m256 v1);
Arguments
*p_cos
points to vector of cosine results (pointer must be aligned on 16 bytes, or declared as
__m128*
instead)
v2
vector with float32 values
Description
Calculates sine and cosine values of vector
v1
elements.
The cosine and sine values cannot be returned in the result vector. Therefore, the intrinsic stores the cosine values at a location pointed to by
p_cos
, and returns only the sine values in the 128-bit result vector.
Returns
128-bit/256-bit vector with the sine results.
Many routines in the
svml
library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
