Synopsis
_mm512_maskz_cvt_roundepi64_pd(__mmask8 k, __m512i a, int rounding);
Description
Convert packed signed 64-bit integers in "a" to packed double-precision (64-bit) floating-point elements, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
