Synopsis
_mm512_mask_rint_pd(__m512d src, __mmask8 k, __m512d a);
Description
Rounds the packed double-precision (64-bit) floating-point elements in "a" to the nearest even integer value and stores the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*64
IF k[j]
dst[i+63:i] := RoundToNearestEven(a[i+63:i])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
