Dear Bernard, I'm studying how it is possible to use your library for the factorization. I have some of questions:
Hello!
- I want to install only the necessary libraries for my aims. I already have GMP and NTL and so I think would be enough GIAC in order to the factorization on rationals, is it true? (I do not work with floating point numbers and I am not interested on graphic's tools.) The installation's process is finished well, even if I have again a doubt: what is DL support which by default is setted to `yes'?
DL support is for dynamic insertion of libraries in a running session of giac/xcas, you can keep giac configure guess safely
- The second question is about the input of an object of the type
`gen': in the little program attached you can see that the use of `n*5' instead of `5*n' caused an ambiguity for operator*. It seems very strange for me this behavior... Is it wanted?
the reason is that I did not overload gen*int, only int*gen, you can use n*gen(5) to force the conversion int -> gen
bye, Bernard Parisse
