The lack of handling root functions in hp prime

[parisse]

While I'm happy to see Xcas compared to Mathematica, it is obvious that I do not have the ressources of Mathematica. There are obviously problems that Mathematica will solve and Xcas will not (but there are also problems that Mathematica will not solve that Xcas solves...).
If you don't like Xcas, nobody force you to use it. Maybe you have noticed that Xcas is free, this is certainly not the case of Mathematica. And comparing Mathematica on a desktop with an Xcas port on a calculator like the Prime is not precisely what I would call a fair comparison.
Now I'm on holiday like many other, I won't comment anymore on your posts.
