Example:

In [1]: from pygeodesy.sphericalNvector import LatLon

In [2]: LatLon(1, 1).nearestOn(LatLon(2, 2), LatLon(2, 2))
Out[2]: LatLon(00°00′00.0″N, 000°00′00.0″E)

Expected output is

Out[2]: LatLon(02°00′00.0″N, 002°00′00.0″E)

Tried with versions 17.06.04 and 17.08.24.

Thank you for your report. Version PyGeodesy-17.8.31 has fixes and test cases for that and this issue:

>>> LatLon(2, 2).nearestOn(LatLon(2, 2), LatLon(2, 2)) LatLon(02°00′00.0″N, 002°00′00.0″E)

Version PyGeodesy-17.8.30 has been removed.
