VSCALEPS zmm {k}, zmm, m512
Synopsis
 _mm512_mask_scale_ps(__m512 src, __mmask16 k, __m512 a, __m512i b);
Description
Scales each single-precision (32-bit) floating-point element in "a" by multiplying it by 2**exponent, where the exponent is the corresponding 32-bit integer element in "b", storing results 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] := a[i+31:i] * POW(2.0, FP32(b[i+31:i]))
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:512] := 0
