_mm_erf_pd

Calculates error function. Vector variant of erf(x) function for a 128-bit vector argument of two float64 values.

Syntax

extern __m128d __cdecl _mm_erf_pd(__m128d v1);

Arguments

v1

float64 vector used for the operation

Description

Calculates error function of v1 elements, which is defined as:

erf(x) = 2/sqrt(pi)* integral from 0 to x of exp(-t*t) dt

Returns

128-bit vector with the result of the operation.
