13179	geometry::covered_by and geometry::within not working for certain values	Stanley <stanley.foerster@…>	Barend Gehrels	"''covered_by'' and ''within'' return false even if the point is obviously located within the polygon, as the following code demonstrates:

{{{
#!c++
#include <iostream>

#include <boost/version.hpp>

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
#include <boost/geometry/geometries/polygon.hpp>

typedef boost::geometry::model::d2::point_xy<double> Point;
typedef boost::geometry::model::polygon<Point> Polygon;

int main() {
    std::cout << ""Running Boost in version "" << BOOST_VERSION << std::endl;

    Polygon polygon;
    std::vector<Point> points;

    points.emplace_back(Point(68.3, 35.5));
    points.emplace_back(Point(68.3, 35.6));
    points.emplace_back(Point(70.3, 35.9));
    points.emplace_back(Point(70.3, 35.8));
    Point point(69.2, 35.7);

    boost::geometry::assign_points(polygon, points);

    std::cout << ""Point is covered by polygon: "" << boost::geometry::covered_by(point, polygon) << std::endl;
    std::cout << ""Point is within by polygon: "" << boost::geometry::within(point, polygon) << std::endl;

    return 0;
}
}}}

which gives:

{{{
Running Boost in version 106500
Point is covered by polygon: 0
Point is within by polygon: 0
