    Even float4. You get +/- 0, 0.5, 1, 1.5, 2, 3, Inf, and two values for NaN.

    Come to think of it, the idea of -NaN tickles me a bit. “It’s not a number, but it’s a negative not a number”.

      I think you got that wrong, you got +Inf, -Inf and two NaNs, but they’re both just NaN. As you wrote signed NaN makes no sense, though technically speaking they still have a sign bit.

        Right, there’s no -NaN. There are two different values of NaN. Which is why I tried to separate that clause, but maybe it wasn’t clear enough.
