Forced rounding create precision troubles
Good morning, Dear GeoGebra and GeoGebrians.
Forced rounding create precision troubles when need to exact draw values with periodic digits for: segments, squares, areas, etc.
According to Pythagoras Theorem, we should sum areas of two squares something like that.
It should be 0.999..., if 2/9 + 7/9 = 0.222... + 0.777... = 0.999...
See attached picture for details, there we could see that area is equal one instead of 0.999....
