In several cases it does not work:

unary operator-(nan)
operator<<(neagative nan) See https://godbolt.org/z/hh8EsarKd At godbolt there seems to be a problem with mpfr right now, so I had to comment out this case.

thx Gero

Sorry I missed this issue at first Gero (@gpeterhoff).

Are you saying that the handling of the sign bit for NaNs is the first point of the issue?
