# _mm_sincos_pd, _mm256_sincos_pd

Calculates the sine and cosine values. Vector variant of sincos(x, &sin_x, &cos_x) function for a 128-bit/256-bit vector with float64 values.

## Syntax

extern __m128d _mm_sincos_pd(__m128d *p_cos, __m128d v1);

extern __m256d _mm256_sincos_pd(__m256d *p_cos, __m256d v1);

## Arguments

*p_cos | points to vector of cosine results (pointer must be aligned on 16 bytes, or declared as __m128d* instead)
v1 | vector with float64 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 byp_cos, and returns only the sine values in the 128-bit result vector.

## Returns

128-bit/256-bit vector with the sine results.

### Note

Many routines in the Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
