Synopsis
_mm512_max_round_pd(__m512d a, __m512d b, int sae);
Description
Compare packed double-precision (64-bit) floating-point elements in "a" and "b", and store packed maximum values in "dst". [sae_note][max_float_note]
Operation
FOR j := 0 to 7
i := j*64
dst[i+63:i] := MAX(a[i+63:i], b[i+63:i])
ENDFOR
dst[MAX:512] := 0
