NaNs do not have signedness.
From IEEE-754 standard: Conversion of a quiet NaN in a supported format to an external character sequence shall produce a language-defined one of “nan” or a sequence that is equivalent except for case (e.g., “NaN”), with an optional preceding sign. (This standard does not interpret the sign of a NaN.)
