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.)
