The lack of handling root functions in hp prime

[parisse]

I fully understand that yangyongkang can have problems to write in English (since I have too). However he choosed to report about advanced and sometimes complicated inputs (some of them were probably not typed on the calculator) and he did not mention about the software warnings when he wrote the topic of title "This time XCAS and hp prime are really wrong! ! !". Look at this title : it's like he is happy to eventually find a defect in Xcas (after several trials where Xcas was just running forever). And everywhere he reports about the same computations with Wolfram Alpha or Mathematica, that really looks like a comparison. DrD did also compare with Wolfram Alpha in the topic "Eigenvectors", assuming de facto that Wolfram Alpha answer was the best possible answer, I had to post twice to explain that it is not.
So yes, I react, and I believe that everyone would react too.

Now let's make things clear: I'm open to bug reports and improvement suggestions and I do my best to take them in account. But I would appreciate a more friendly tone. Remember that Giac/Xcas is a free software, not a commercial one (not to say that commercial softwares should be criticized harder than free ones, but they usually do not participate in open forums like here or they give less informative answers because the developers do not participate themselves). One can of course argue that the HP Prime port is commercial, but in reality ask yourself how CAS improvements and bug fixes are done. And keep in mind that my ressources and priorities in Xcas are not the same as Mathematica.
