Problem with the numeric format.

[math7]

Something strange happens with my physical calculator, but it also happens in the Prime in android, the problem is that when I'm in CAS mode and for example I establish the numerical format in engineering, or fixed or scientific with any number of decimals the calculator does not respect this, but presents the results but according to how the format is in the HOME mode. So why is both settings independent, if in the long run only the format of the HOME mode is the one that also predominates in the CAS mode, or is it something wrong with the calculator and the virtual application in Android? I already updated my Prime to the latest version number 13865. This also happened in the previous version.
