The value you are trying to determine the sign for is a sixteen bit number.

Every number that your ng output is for has exactly sixteen bits.

So, if I give you a 16-bit value, you should be able to look at it and immediately say whether or not ng should be HI or LO.

Look at that list of ten 16-bit numbers I posted. You should literally be able to walk down that entire list in under five second and say, "False, True, False, True, True, False, True, True, False, False," as the value for ng for each line in turn.
