_mm_exp2_ps, _mm256_exp2_ps
Calculates exponential value of 2. Vector variant of exp2(x) function for a 128-bit/256-bit vector argument of float32 values.
Syntax
extern __m128 _mm_exp2_ps(__m128 v1); |
extern __m256 _mm256_exp2_ps(__m256 v1); |
Arguments
v1 |
vector with float32 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 Short Vector Math Library (SVML) are more optimized for Intel® microprocessors than for non-Intel microprocessors.
