Prime with cocoa
Enjoy your Prime with cocoa! Try this in CAS:
convert(0,14) Must be typed in lowercase. CAS only. <0ΙΈ0> Joe

RE: Prime with cocoa
Nice one!
Mine did the same, using the most recent firmware update (Nov25). After typing "convert(0,14)" in CAS window, the answer was prompted in the history area as: "CONVERT(0,14) with_cocoa" Surely the calculator must have a good reason for this kind of recommendation. I enjoy chocolate very much, thank you! After checking the wikipedia, apparently this can be related to the COCOA API framework?

RE: Prime with cocoa
Strange or interesting at least!
convert(1,14) > with_f5 convert(2,14) > tdeg convert(3,14) > plex convert(4,14) > revlex convert(5,14) > modular_check convert(6, 14) > 6 This seems to be related to xCAS which is the base for the CAS on the HP Prime: http://wwwfourier.ujfgrenoble.fr/~pari...en232.html CoCoA has nothing to do with Cocoa on OSX and it is a system for computing with multivariate polynomials. http://cocoa.dima.unige.it/flyer4.html Further, CoCoA is part of xCAS.

RE: Prime with cocoa
Thanks for the enlightenment, Dominik!
That explanation makes all the sense now. I guess I have a long way in front of me to learn all this advanced CAS/xCAS framework. I did symbolic calculus at school in my time, long ago, but never used machines for that purpose, except of course for numeric operations with my HP25 Jose Mesquita Jose Mesquita RadioMuseum.org member

RE: Prime with cocoa
Yes, CoCoA was the Groebner basis computation engine of giac before I implemented my own engine (that is now the fastest opensource Groebner basis engine for revlex ordering). with_cocoa is still an optional argument that you can pass to gbasis in Xcas to force use of CoCoA.
