Comment(by SimonKing):
`float('nan')` does not result in an error. Comparison must not result in
an error, according to Python specifications, if I remember correctly.
Hence, using sigon/sigoff seems the wrong thing to do, because of the
raised floating point error. In addition: Wouldn't sigon/sigoff slow the
code down? I don't know by how much, though.
