_mm_pow_pd, _mm256_pow_pd

Calculates exponential value of one argument raised to the other argument. Vector variant of pow(x, y) function for a 128-bit/256-bit vector argument of float64 values.

Syntax

extern __m128d _mm_pow_pd(__m128d v1, __m128d v2);

extern __m256d _mm256_pow_pd(__m256d v1, __m256d v2);

Arguments

v1

vector with float64 values

v2

vector with float64 values

Description

Calculates the exponential value of each vector v1 element raised to the power of the corresponding vector v2 element.

Returns

128-bit/256-bit vector with the result of the operation.

NOTE:

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