NaN Vs None

In choosing a way to represent a value of "no information" for a float, would it be better to use NaN or None? None has the advantage of standard behavior across platforms, but NaN seems to propagate more easily - at least on Windows.
For example,
NaN+1 = NaN
but
None+1
raises an exception.
Thanks in advance for any advice.
