CGAL 4.12.1  Number Types

#include <CGAL/leda_real.h>
The class leda_real
is a wrapper class that provides the functions needed to use the number type real
, representing exact real numbers numbers provided by LEDA.
The class leda_real
provides exact computation over the subset of real numbers that contains integers, and which is closed by the operations \( +,,\times,/,\sqrt{}\) and \(\sqrt[k]{}\). For LEDA version 5.0 or later leda_real
is also able to represent real roots of polynomials. Operations and comparisons between objects of this type are guaranteed to be exact.
For more details on the number types of LEDA we refer to the LEDA manual [Solutions].
