Well, no. 1E400 requires only one bit of precision, but it's not representable as a double, because doubles only go up to 1E308 or so. > > The trouble with all this is that They Break Data. > > I care -Inf about this. That reminds me how *annoying* it is that there's no way to represent Inf, -Inf, or NaN.
