How to display exact result on CASIO calculator fx-82DE X?

Hey, as asked above, I wanted to know how I can get an exact result on my CASIO calculator fx-82DE X.

For example, mixed fractions and results with ln or e. I have a math exam tomorrow, and these exact results are incredibly important, and these numerical values ​​are useless :/

At e and ln you will not be lucky in most cases.

Otherwise “shift” “mode” offers some possibilities.

With e, this is just wrong, which is also an irrational number.
