Synopsis
_mm256_maskz_cvtpd_ph(__mmask8 k, __m256d a);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed half-precision (16-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). The upper 64 bits of "dst" are zeroed out.
Operation
FOR j := 0 TO 3
IF k[j]
dst.fp16[j] := Convert_FP64_To_FP16(a.fp64[j])
ELSE
dst.fp16[j] := 0
FI
ENDFOR
dst[MAX:64] := 0
