VEXP223PS zmm, zmm
Synopsis
_mm512_exp223_ps(__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".
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := exp223(v2[i+31:i])
ENDFOR
dst[MAX:512] := 0
