CGAL::Rational_traits< NT > Class Template Reference

#include <CGAL/Rational_traits.h>


The class Rational_traits can be used to determine the type of the numerator and denominator of a rational number type as Quotient, Gmpq, mpq_class or leda_rational.


typedef unspecified_type RT
 the type of the numerator and denominator.


RT numerator (const NT &r) const
 returns the numerator of r.
RT denominator (const NT &r) const
 returns the denominator of r.
NT make_rational (const NT &x) const
 returns self.
NT make_rational (const std::pair< RT, RT > &p) const
 constructs a rational number p.first/p.second.
NT make_rational (const RT &n, const RT &d) const
 constructs a rational number.
NT make_rational (const NT &n, const NT &d) const
 constructs a rational number.
