As a historical note, this is a primary reason why digital computers replaced analog computers. If you want another digit of accuracy out of an analog computer, you need components that are 10 times as accurate, requiring expensive precision resistors and capacitors. But if you want another digit of accuracy out of a digital computer, you just process four more bits and you can still use cheap, inaccurate components. While analog computers are almost entirely forgotten now, they were widely used even into the 1970s. They could solve differential equations almost instantaneously, while digital computers needed to chug through calculations before producing the answer. But digital computers steadily became faster until they could generate answers in real-time, but more accurate and easier to program.
