If you use GPL Setup Manager, it should make it pretty clear. The setup manager labels the boxes "Toe In, in" on my screen (I use "English" units in inches). So positive values turn the wheels inwards, towards each other, and vice-versa.
At the front, to help the cars turn into corners, I always use some
negative toe, which means toe
out, which has the front wheels pointing slightly outwards from each other. (Using your terminology I think that would make the front wheels
divergent.)
At the rear, to help stability, I always have a small amount of
positive toe, which means toe
in, which has the rear wheels pointing slightly inwards, towards each other. (Again, using your terminology, I think that makes the rear wheels
convergent.)
I hope that's nice and clear.
