_mm512_getexp_ps/ _mm512_mask_getexp_ps

Extract float32 vector of exponents. Corresponding instruction is VGETEXPPS. This intrinsic only applies to Intel® Many Integrated Core Architecture (Intel® MIC Architecture).

Syntax

Without Mask

extern _m512 __cdecl _mm512_getexp_ps(_m512 v2);

With Mask

extern _m512 __cdecl _mm512_mask_getexp_ps(_m512 v1_old, __mmask16 k1, _m512 v2);

Parameters

v2

float32 vector used for the extract 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

Extracts float32 vector of exponents from vector v2.

The masked variant has one additional argument: k1. Only those elements in the source registers with the corresponding bit set in vector mask k1 are used for computing.

Returns

Returns the result of the operation.
