CGAL::make_root_of_2

Definition

The function make_root_of_2 constructs an algebraic number of degree 2 over a ring number type.

#include <CGAL/Root_of_traits.h>

template <typename RT>
Root_of_traits<RT>::RootOf_2	make_root_of_2 ( RT a, RT b, RT c, bool s)
		Returns the real root of the polynomial $$aX2+bX+c which is the smallest if $$s is true, or the largest if $$s is false. Precondition:  RT is a RingNumberType. Precondition:  The polynomial has at least one real root.
template <typename RT>
Root_of_traits<RT>::RootOf_2	make_root_of_2 ( RT alpha, RT beta, RT gamma)
		Constructs the number $$+ sqrt(). Precondition:  RT is a RingNumberType. Precondition:  $$ 0
