_mm256_exp_ps

Calculates exponential value of
e
(base of natural logarithms). Vector variant of exp(x) function for a 128-bit/256-bit vector argument of float32 values.

Syntax

extern __m128 _mm_exp_ps(__m128 v1);
extern __m256 _mm256_exp_ps(__m256 v1);
Arguments
v1
vector with float32 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.
