_mm_sincos_pd

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

Syntax

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

Arguments

*p_cos

points to vector of cosine results (pointer must be aligned on 16 bytes, or declared as __m128d* instead)

v1

128-bit 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 by p_cos, and returns only the sine values in the 128-bit result vector.

Returns

128-bit vector with the sine results.
