Calculates signed exponent. Vector variant of logb(x) function for a 128-bit/256-bit vector argument of float32 values.

Syntax

extern __m128 _mm_logb_ps(__m128 v1);

extern __m256 _mm256_logb_ps(__m256 v1);

Arguments

v1

vector with float32 values

Description

Returns the signed exponent for vector v1 elements.

Returns

128-bit/256-bit vector with the result of the operation.

Note

Many routines in the svml library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
