The a b/c key

[math7]

Hello everyone!!! And I was thinking about what Joe and Han said but analyzing the subject a bit more, as far as the a / b / c key that does not work the same in the CAS as in the HOME MODE, I think it has nothing to do The mathematical algorithm used in each mode. I meant at the beginning that in CAS mode the key a b / c does not deliver the result as a mixed fraction of any result. This does not have to do with the algorithm, but simply to move from an improper fraction to a mixed one is simply that the HP Prime does the conversion as done for example by hand, or the same as does the propfrac command that indicated me Joe and who does deliver the mixed fraction for example 89/77 = 1 + 12/77.

This result does not have to do with the algorithm that is used in the CAS, but the calculator after obtaining the result 89/77 expresses it as 1 +12/77 either by calling internally the propfrac command or another method, but Screen is displayed by pressing the ab / c key as in HOME mode.
