* @param[out] M21 geodesic scale of point 1 relative to point 2

* @param[out] S12 area under the geodesic (meters<sup>2</sup>).
* @return \e a12 arc length of between point 1 and point 2 (degrees).
*
* \e lat1 and \e lat2 should be in the range [−90°, 90°].
* The values of \e azi1 and \e azi2 returned are in the range
* [−180°, 180°).
*
* If either point is at a pole, the azimuth is defined by keeping the
* longitude fixed, writing \e lat = ±(90° − ε),
* and taking the limit ε → 0+.
*
* The following functions are overloaded versions of GeodesicExact::Inverse
* which omit some of the output parameters. Note, however, that the arc
* length is always computed and returned as the function value.
