CGAL::Rational_traits< NT > Class Template Reference

#include <CGAL/Rational_traits.h>

Definition

template<typename NT>
class CGAL::Rational_traits< NT >

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.

Types
typedef unspecified_type	RT
	the type of the numerator and denominator. More...

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