--- Comment #2 from Roberto Bagnara <bagnara at cs dot unipr.it> ---
I agree correct rounding is the goal of other functions. But here I am
advocating a much weaker property that still has a lot of value for
applications: monotonicity. This goal is almost attained by exp2f(): there are
only a handful of unwanted decreases and they all amount to just one ULP.
