#### strategy::distance::pythagoras

Strategy to calculate the distance between two points.

###### Synopsis

    template<typename Point1, typename Point2, typename CalculationType>
    class strategy::distance::pythagoras
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
typename Point1 |  | point type
typename Point2 | Point1 | second 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

###### Member Function(s)

Function | Description | Parameters | Returns
--- | --- | --- | ---

    calculation_type apply(Point1 const & p1, Point2 const & p2)

applies the distance calculation using pythagoras

Point1 const &: p1: first point

Point2 const &: p2: second point

the calculated distance (including taking the square root)

Can be used for points with two, three or more dimensions
