I'm not sure, but I suspect this is a helpful method for things in analytic geometry. I.e., if you have a ray and a point, it would allow you to determine the direction to move for the shortest path (in polar coordinates, for example). -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
