Random_points_in_square_2 (double a, Random &rnd=get_default_random())
Creates an input iterator g generating points of type Point_2 uniformly distributed in the half-open square with side length $$2 a$$, centered at the origin, i.e. $$\forall p = *g: -a \le p.x() < a$$ and $$-a \le p.y() < a$$. More...

template<typename Point_2 , typename Creator >
 CGAL::Random_points_in_square_2< Point_2, Creator >::Random_points_in_square_2 ( double a, Random & rnd = get_default_random() )

Creates an input iterator g generating points of type Point_2 uniformly distributed in the half-open square with side length $$2 a$$, centered at the origin, i.e. $$\forall p = *g: -a \le p.x() < a$$ and $$-a \le p.y() < a$$.

Two random numbers are needed from rnd for each point.
