Synopsis
_mm512_maskz_cvtph_epi64(__mmask8 k, __m128h a);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed 64-bit integers, 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
IF k[j]
dst.qword[j] := Convert_FP16_To_Int64(a.fp16[j])
ELSE
dst.qword[j] := 0
FI
ENDFOR
dst[MAX:512] := 0
