In that case decimal is flawed too, 0.6667 or any such approxination doesnt exactly equal 2/3. It technically happens in any number system where you are dividing by a prime that isnt part of either the base or the number being divided
Define "all the other numbers". Do we include only natural numbers? Or all instegers? Or even rational numbers? Do we include imaginary numbers? How about complex numbers? Orbetter go for quaternions?
