rounding to two significant figures?
I make a geogebrafile to illustrate a geometric excercise for my students, and want the figure to have two significant figures. How do I do it? In preferences, I can chose 3, 5 or 10 significant figures, but I want 2.
A related problem, I often want a triangel with 1 desimals in lines, but 0 desimals in angels. Can it be done?
