_mm_log2_ps, _mm256_log2_ps
Calculates base-2 logarithm. Vector variant of log2(x) function for a 128-bit/256-bit vector argument of float32 values.
Syntax
extern __m128 _mm_log2_ps(__m128 v1); |
extern __m256 _mm256_log2_ps(__m256 v1); |
Arguments
v1 |
vector with float32 values |
Description
Calculates the base-2 logarithm 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.
