If we want to be really pedantic, a computer does not necessarily need to be digital. You could build a consciousness-coprocessor with analog circuitry that brings in what you say could be needed. But honestly I doubt that there is a real requirement for that, surely you could just increase the resolution you're running the simulation at until the difference decreases sufficiently. Imagine using 256 bit floats for example.
