Periode van een rationaal getal

Hello,

Bestaat er een commando om de periode van een rationaal getal te bepalen?

Voorbeeld:

De periode van 5/6 is 3.

De periode van 7/13 is 538461.

Hoe de periode van 4/17 bepalen?

Bedankt!

Rodger.

Why do you need that? What are you trying to make?

It's a common exercise in algebra to define the period, like e.g. in https://www.geogebra.org/m/M3q7uuSd. In GeoGebra it is possible to create such exercises with some puzzling, creating a few variations oneself, but of course if you could define the period of a random fraction it would be more practical and general.

Hello Michael,

Hello Chris,


I think it would be very interesting for many students to have a command for that problem.

I doubt we'll add that - you could make a custom tool I think.
