Well, but on the other hand, what happens when you do things like 1.0 + NaN or NaN + 1.0? Â It should work...
Easy with double dispatching. More boring is to coerce a (Float nan) created by a call to an external library into a (Smalltalk at: #Nan).

Would NaN be polymorphic with floats?
Do you mean , be a part of Number/Float class hierarchy? Answer is: no. Because NotANumber is not a number :)
