The special case of 1/0 is less clear, though. One might decide that it should be an error rather than NaN, as some languages have.

It is neither,

1/0 = Infinity -1/0 = -Infinity

Just out of curiosity:

1/-0 = -Infinity? -1/-0 = Infinity?

Yes. (You could have tried this for yourself, you know... but I suppose haskell-cafe isn't a bad interactive Haskell interpreter, perhaps more user friendly than ghci.) -- David Roundy Department of Physics Oregon State University
