_mm_log1p_ps, _mm256_log1p_ps
Calculates natural logarithm. Vector variant of log1p(x) function for a 128-bit/256-bit vector arguments with float32 values.
Syntax
extern __m128 _mm_log1p_ps(__m128 v1); |
extern __m256 _mm256_log1p_ps(__m256 v1); |
Arguments
v1 |
vector with float32 values |
Description
Returns the natural logarithm of vector v1 elements, defined by:
ln (v1 + 1)
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.
