_mm512_div_pd/ _mm512_mask_div_pd

Calculates quotient of a division operation. Vector variant of div() function for float32 arguments. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).

Syntax

Without Mask

extern _m512d __cdecl _mm512_div_pd(_m512d v2, _m512d v3);

With Mask

extern _m512d __cdecl _mm512_mask_div_pd(_m512d v1_old, __mmask8 k1, _m512d v2, _m512d v3);

Parameters

v2

float64 vector used for the division operation

v3

float64 vector also used for the division operation

v1_old

Source vector that retains old values of the destination vector; the resulting vector gets corresponding elements from v1_old for zero mask bits

k1

Writemask; only those elements of the source vectors with corresponding bit set to '1' in the k1 mask are computed and stored in the result; elements in the result vector corresponding to zero bit in k1 are copied from corresponding elements of vector v1_old

Description

Performs an element-by-element division between float64 vector v2 and float64 vector v3.

The masked variant has two divisional arguments: v1_old and k1. Those elements of v2 and v3 with the corresponding bit clear in vector mask k1 are not used in the computation. Instead, the corresponding element from v1_old is copied to the resulting vector.

Returns

Returns the result of the division operation.
