Synopsis
_mm512_maskz_cvtepu64_pd(__mmask8 k, __m512i a);
Description
Convert packed unsigned 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).
Operation
FOR j := 0 to 7
i := j*64
IF k[j]
dst[i+63:i] := Convert_Int64_To_FP64(a[i+63:i])
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:512] := 0
