It’s a very interesting article that’s based entirely on a flawed premise, that floating point is the only way to represent numbers in a computer. It’s true that there are numbers that can’t be represented by a computer using any system, but they are so huge that you probably couldn’t represent them any other way either (say a random number with a quadrillion digits, since a billion digits is totally possible and a trillion is pushing it on consumer hardware. Even then, it could probably be done with a million bucks of hardware).
