Synopsis
_mm512_maskz_div_round_pd(__mmask8 k, __m512d a, __m512d b, int rounding);
Description
Divide packed double-precision (64-bit) floating-point elements in "a" by packed elements in "b", and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
