_mm_logb_pd, _mm256_logb_pd
Calculates signed exponent. Vector variant of logb(x) function for a 128-bit/256-bit vector argument of float64 values.
Syntax
extern __m128d _mm_logb_pd(__m128d v1); |
extern __m256d _mm256_logb_pd(__m256d v1); |
Arguments
v1 |
vector with float64 values |
Description
Returns the signed exponent for 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.
