#### strategy::within::crossings_multiply

Within detection using cross counting,.

###### Synopsis

    template<typename Point, typename PointOfSegment, typename CalculationType>
    class strategy::within::crossings_multiply
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
typename Point |  | Any type fulfilling a Point Concept
typename PointOfSegment | Point | segment point type
typename CalculationType | void | numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point
