Edit: but is it possible to add the rational number square(2) = 1,414213562... , instead the approximative result number with only 2 digits = 1.41 - by default ???

By this way it will be possible to have the whole values:
...50%,71%,100%,...%, 200%, ...,400%,..., 800%,..., 1600%,...

Instead the actual approximate values:
...51%,71%,100%,...%, 199%, ...,396%,..., 786%,..., 1563%,...
