It would be nice if the current function, without performance penalty,
were ultimately renamed to unsafeDecodeFloat.

A new function could return something like
    data DecodedFloat = Decoded Integer Int
                      | NaN
                      | Infinity
                      | NegativeInfinity
                      | NegativeZero
(I'm not sure which constructors you'd want exactly).


Thanks
