I have been using print_latex and I found that the following piece of code
#include <iostream> #include <ginac/ginac.h>
using namespace std; using namespace GiNaC;
int main() { GiNaC::ex q;
q = 2 * pow(6, numeric(1,3));
q.print(print_latex(std::cout));
}
produces the output
2 6^{{(\frac{1}{3})}}
which latex then typesets in the wrong way, since the space is lost. Putting a \cdot in place of the blank seems to fix the problem.
Hmm, I am somewhat reluctant to introduce a "\cdot" there. Putting parenthesis around 6^(1/3) in LaTeX-output would either bloat the printing routines or bloat the normal output with superfluous parenthesis as well, as in 2(x^2) instead of 2 x^2. May I suggest to change the space to a hard space "\ " in LaTeX? This would then produce 2\ 6^{{(\frac{1}{3})}} which seems legible to me, when typeset. (Try it with a two-digit basis.) Would that be okay for you folks? Regards -richy. PS: It's a real pity LaTeX is dedicated to printed format instead of semantical format. :-( -- Richard B.
