e behavior of signaling NaNs. NaNs
          created by IEC 60559 operations are always quiet. Therefore this implementation
          follows C99, and treats the signaling NaN bit as just a part of the NaN
          payload field. So this implementation does not distinguish between the
          two classes of NaN.
