Synopsis
_mm512_maskz_cvt_roundpd_epu64(__mmask8 k, __m512d a, int rounding);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed unsigned 64-bit integers, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
