[GiNaC-list] Number representation

 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.
