Synopsis
 _mm512_maskz_fnmadd_round_ps(__mmask16 k, __m512 a, __m512 b, __m512 c, const int rounding);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", add the negated intermediate result to packed elements in "c", 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 j := 0 to 15
	i := j*32
	IF k[j]
		dst[i+31:i] := -(a[i+31:i] * b[i+31:i]) + c[i+31:i]
	ELSE
		dst[i+31:i] := 0
	FI
ENDFOR	
dst[MAX:512] := 0
