_mm256_exp2_pd

Calculates exponential value of 2. Vector variant of exp2(x) function for a 128-bit/256-bit vector argument of float64 values.

Syntax

extern __m128d _mm_exp2_pd(__m128d v1);
extern __m256d _mm256_exp2_pd(__m256d v1);
Arguments
v1
vector with float64 values
Description
Calculates the exponential value of 2 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.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
