NaNs are an area where it's easy for someone ignorant to screw up. Would some of you guys who know and care about numerics like to come up with a concrete code change -- maybe it's only one line in the definition of decodeFloat -- and then we'll apply it? Ideally a patch, but it'd be good enough to say "change this line to say that".

Oh, and please give us a test or two with expected output.
