Hello, I am new to ginac. At the moment I am playing with the tool trying to compute finite element bases as in SyFi. As a solution of a system of linear equations I got: {b0_0==0.25,b0_1==-0.25,b0_2==-0.25,b0_3==0.25} But I would have wanted the fraction 1/4 instead of 0.25. How can I force ginac to not compute fractions ? Thank in advance.
