#### strategy::distance::projected_point

Strategy for distance point to segment.

###### Description

Calculates distance using projected-point method, and (optionally) Pythagoras

###### Synopsis

    template<typename CalculationType, typename Strategy>
    class strategy::distance::projected_point
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
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
typename Strategy | pythagoras<CalculationType> | underlying point-point distance strategy
