Googling NaN and IEEE754 will produce an explanation of this, since you don't 
believe me :-) The explanation is NaN is never equal to anything, so NaN!=0 is true.

I implemented NaN behavior in the 1980s, and was very scrupulous in doing it 
exactly according to the spec, regardless of what I thought would be better. If 
I had done it differently, I would have been subject to endless complaints.
