</blockquote><br>That depends on what you mean. If a computer running Mathematica is solving a difficult equation symbolically not numerically would you call that a digital solution, and if is digital and a human solves the same equation and gets the same answer would that still be a digital answer? And If a digital computer is simulating a analog computer (and they can do so with much much higher precision than a real analog computer can in a sense simulate itself) is it still a purely digital platform? <br>
