Converting between Rational and Floating Point KernelFloating point objects can be converted to rational objects, and vice versa. We illustrate conversion for points.If If Remark 1: The conversion from rational objects to floating point
objects needs to be used whenever an object is to be displayed in a window.
If Example:#include <LEDA/graphics/window.h> #include <LEDA/geo/rat_point.h> using namespace leda; int main() { rat_point rp(50,50); window W(100,100); W.open(); W << rp.to_point(); //W << rp; does not work W.display(); W.read_mouse(); return 0; } Remark 2: We could write |
