Instruction
VGETEXPPS zmm, zmm {sae}
Synopsis
 _mm512_getexp_round_ps(__m512 a, int sae);
Description
Convert the exponent of each packed single-precision (32-bit) floating-point element in "a" to a single-precision (32-bit) floating-point number representing the integer exponent, and store the results in "dst". This intrinsic essentially calculates "floor(log2(x))" for each element. [sae_note]
Operation
FOR j := 0 to 15
	i := j*32
	dst[i+31:i] := ConvertExpFP32(a[i+31:i])
ENDFOR
dst[MAX:512] := 0
