===================================
> I was mistaken, choosing the angle via the below contract, one gets all values up to 90^o (cf. the entry "angle between two lines"):
> textbooks one says that the "suuntakulma" is the _acute_ angle which the line forms with the x-axis, equipped with minus sign if the line descends to the right
"acute" is wrong, it must be "least"! Then one gets all values up to 90^o.
