This is not my area of specialty, so correct me if I'm wrong, but isn't it the case that we can determine whether to numbers are inequal? If so, then isn't also

- lmm 14y agoWe can determine some of the time. You can ask "does a equal b?" and your answer will either be "no" or "maybe" So you can't even say that a number is equal to itself. You can't use it as an index into another datastructure. Doing physics gets hard because you can never say whether two objects have collided. Just about the only thing you can do with these numbers is print them out or plot them on a graph - and you have to discretize to do that - so all it really gives you is a very expensive way to make sure you never lost any precision through all your intermediate calculations.
