Dear all, while working with print_latex(), I found the following unexpected behaviour: the expression `p' is assigned the value 1/2-1/2*I, but then it is transformed into the following latex form: \frac{1}{2}\frac{-1}{2} i I am using version 1.0.11. Best wishes Alessandro Zaccagnini #include <iostream> #include <ginac/ginac.h> using namespace GiNaC; int main() { GiNaC::ex p; p = numeric(1)/2 + numeric(-1)/2*I; std::cout << p << " "; p.print(print_latex(std::cout)); return 0; }
