Digital calculators don't model uncertainty in the same way that mechanical ones do. I would love a calculator that intuitively does tolerance proposition. The point here isn't a out precision, its about accuracy. Most simulations consider tolerances and variability as an afterthought, and as you point ouf spitting out a seemingly precise but likely innacurate output. Really we should have the best of both worlds - simulations should model uncertainty or use MTCS, and output a probability range.
