 different types, such
          as a boost::tuple&lt;float, double&gt;. Boost.Geometry reports the first
          type as its <a class="link" href="../core/coordinate_type.html" title="coordinate_type">coordinate_type</a>.

          Boost.Geometry supports Boost.Tuple pairs, triples, quadruples, etc up
          to tuples with 10 elements (though most algorithms do not support so many
          dimensions).

          A tuple can be the point type used by the models linest
