Synopsis
 _mm512_maskz_mul_round_ph(__mmask32 k, __m512h a, __m512h b, int rounding);
Description
Multiply packed half-precision (16-bit) floating-point elements in "a" and "b", and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). [round_note]
Operation
FOR i := 0 TO 31
	IF k[i]
		dst.fp16[i] := a.fp16[i] * b.fp16[i]
	ELSE
		dst.fp16[i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
