They're different using this approach, so what is the better type I have to use to get exact computing of intersection between lines? I've made "typedef double NT", do I just need to change "double" with another type to get the project compile yet? Thanks in advance.

Sterpa a écrit :

I have this two points
1.1 -2.08 - 1.1 -2.08

and this is the output of CGAL::compare_y(point1, point2);

-1 (SMALLER)

how can this happen?
I've tried other approach such as a simple point1.y() != point2.y() or just
point1 != point2, but I never got the wrong output (which is "EQUAL"). Do I
need to use another function?

Does it still print the same .y() values if you do the following ?

 std::cout.precision(20);
