Did not realize that 0 * Infinity is NaN. Anyone know why that wouldn't be expected to be 0?

oh no, I checked the spec and it also allowed negative zero so I don't know what to believe now.

That one actually has reasoning behind it at least. If 0 were unsigned, 1 / (1 / x) == x wouldn't hold for all values of x

except I now learn that 0 == -0 but 1/0 != 1/-0. I guess the moral of the story is that is floating point math isn't math.

So our domain *must* include 0, and that property has to hold. Hence signed 0
