Increasing number of Decimals Dynamically
Answered
I have this worksheet.
https://www.geogebra.org/m/1457011
As far as I know these conditions always hold true. However a colleague of mine pointed out a situation where it seems to not hold true.
The problem is that it just cannot be seen with 2 decimal places but the condition is still true. Can I dynamically change the number of decimals shown on screen?

I am not aware of a way to dynamically change rounding/significant digits, unless you allow menus to be in your app...Options allows you to change rounding.

Possibly,
Thanks for the reply, I will see how I can use this to solve my problem! Thanks.
Maybe create my own buttons or slider that allow the user the increase and decrease the number of Significant Figures!
Problem with this. It is only available in CAS view, I need the numbers visible on the worksheet, is this possible with the numeric command?
Hi,
you can't do it with labels, but it should work with texts (you can hide labels and replace them with texts, so this is no big problem).
* define the number n of decimal places you want to use: either use a slider and let user change it or compute it yourself using something like
minDiff=Min[KeepIf[x>0,{abs(ab),abs(bc),abs(ca)}]]
n=Max[ceil(log10(minDif)),1]
* open properties of your text, make sure it's not fixed
* set the rounding to something big, eg. 10 decimal places
* replace a,b,c with round(a,n), round(b,n), round(c,n)
Cheers,
Zbynek
The file attached demonstrates the formula for c < a < b case, other 5 cases should be easy to adjust.

Cool, thanks a lot! I'm going to try implementing this with a slider to give the user control.
