The easiest and fastest solution would be to return infinity of the same sign, as that allows inf, -inf and NaN to be checked with a single comparison (all the exponent bits equal 1). Since infinity is such an abnormal value to get the fractional component for, this is an acceptable return in my opinion. Gareth aka.
