Calculates natural logarithm. Vector variant of log1p(x) function for a 128-bit/256-bit vector arguments with float64 values.

Syntax

extern __m128d _mm_log1p_pd(__m128d v1);

extern __m256d _mm256_log1p_pd(__m256d v1);

Arguments

v1

vector with float64 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.
