RE: Xcas Syntax / Prime Syntax (in particular computing in Z/pZ)
Some clarifications:
Xcas has several syntax compatibility modes: maple, geogebra, ti, hp, that you can change with the xcas_mode and calc_mode commands. For example, calc_mode(-38) on Xcas will somewhat simulate the Prime syntax compatibility mode, this make it easier for me to fix bugs for the Prime CAS. The Prime CAS parser does not recognize all the keywords that are recognized by Xcas. xcas_mode and calc_mode are not recognized on the Prime, you can not switch to Maple compatibility mode on the Prime. In addition, some keywords differ, like %, because % is a keyword on the HP. That's why on the Prime, you must use %% instead of % if you want to work in Z/pZ. For uppercase/lowercase commands: (almost) all the genuine HP38 uppercase commands are built-in CAS commands, which means no conversion happens if you are using them from the CAS. New Prime uppercase Home commands are not built-in CAS commands, if you are using them from the CAS, the call to the Home command is done with conversion to Home objects. |
