On ubuntu, tostring(1/0) gives "inf", and tonumber("inf") gives a number that's indeed the representation for infinite.
So for some systems, you can in fact put back into Lua what you get out (by going through tonumber)

Correct me if I'm wrong on some point here - but 1.#INF isn't Lua syntax. It's just a way of printing the value you get from 1/0. So it only works one way; you can't put it back into Lua because it's not a valid Lua _expression_.
