Re: [GiNaC-list] custom print function for GiNaC::add and GiNaC::mul for deterministic printing

Dear Vladimir, thanks for your answer. I think it will work and this would be my fallback, but it will convert each expair in an ex, which I then have to check again for the sign of the coefficient, or whether it is a negative power in mul, and so on. I just wanted to make sure a priori whether there is a better way directly working on the expairs, but if not, I'll go over the op() of course.

Dear Christian,

Just a quick question: why does expairseq::op() method (inherited by sums and muls, I think) will not work for you?

Best wishes, Vladimir
