Yes, I've seen it, and in a previous-unrelated post I commented I 
am planning to use it (or something similar) because floats and 
currency are a horrible combo. I am not using it right now 
because I want to learn the language and encountering situations 
like this one helps me a lot, otherwise, I would have never noted 
such NaN behavior -to me, there are a lots of things that could 
fly under the radar at this moment. And by the way, looking at 
the code, money seems a quite simple non-nonsense implementation 
making it a solid candidate :)

Thanks for the tip Andre !
