_mm256_exp_pd

Calculates exponential value of
e
(base of natural logarithms). Vector variant of exp(x) function for a 128-bit/256-bit vector argument of float64 values.

Syntax

extern __m128d _mm_exp_pd(__m128d v1);
extern __m256d _mm256_exp_pd(__m256d v1);
Arguments
v1
vector with float64 values
Description
Calculates the exponential value of
e
(base of natural logarithms) raised to the power of vector
v1
elements.
Returns
128-bit/256-bit vector with the result of the operation.
Many routines in the
svml
library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
