leda_real Class Reference

#include <CGAL/leda_real.h>

## Definition

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.
