_mm512_exp_pd/ _mm512_mask_exp_pd

Calculates exponential value of e (base of natural logarithms). Vector variant of exp(x) function for a float64 argument.   This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).

Syntax

Without Mask

extern _m512d __cdecl _mm512_exp_pd(_m512d v2);

With Mask

extern _m512d __cdecl _mm512_mask_exp_pd(_m512d v1_old, __mmask8 k1, _m512d v2);

Parameters

v2

vector with float64 values

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

Calculates the exponential value of e (base of natural logarithms) raised to the power of vector v2 elements.

The masked variant has two additional arguments: v1_old and k1. Those elements of v2 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 operation.
