Synopsis
 _mm512_mask_exp223_ps(__m512 src, __mmask16 k, __m512i v2);
Description
Approximates the base-2 exponent of the packed single-precision (32-bit) floating-point elements in "v2" with eight bits for sign and magnitude and 24 bits for the fractional part. Results are stored in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
	i := j*32
	IF k[j]
		dst[i+31:i] := exp223(v2[i+31:i])
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:512] := 0
