Intel® C++ Compiler 16.0 User and Reference Guide
Calculates natural logarithm. Vector variant of log1p(x) function for a 128-bit/256-bit vector arguments with float64 values.
extern __m128d _mm_log1p_pd(__m128d v1); |
extern __m256d _mm256_log1p_pd(__m256d v1); |
v1 |
vector with float64 values |
Returns the natural logarithm of vector v1 elements, defined by:
ln (v1 + 1)
128-bit/256-bit vector with the result of the operation.
Many routines in the svml library are more highly optimized for Intel® microprocessors than for non-Intel microprocessors.
