Which seems odd.

And internally, this is because the IEEE float machinery guarantees that all infinite and NaN values compare as not-equal to each other, so that 1/0 != 2/0, 1e100 != 1e100 + 1, and so on. Sadly, this also means that some floats will compare as not equal to themselves -- an unfortunate, but necessary result.
