Instruction
VEXP2PS zmm, zmm
Synopsis
 _mm512_exp2a23_ps(__m512 a);
Description
Compute the approximate exponential value of 2 raised to the power of packed single-precision (32-bit) floating-point elements in "a", and store the results in "dst". The maximum relative error for this approximation is less than 2^-23.
Operation
FOR j := 0 to 15
	i := j*32
	dst[i+31:i] := POW(FP32(2.0), a[i+31:i])
ENDFOR
dst[MAX:512] := 0
