Instruction
VRCP28PS zmm, zmm {sae}
Synopsis
 _mm512_rcp28_round_ps(__m512 a, int sae);
Description
Compute the approximate reciprocal 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^-28. [sae_note]
Operation
FOR j := 0 to 15
	i := j*32
	dst[i+31:i] := (1.0 / a[i+31:i])
