Tack så mycket, Lars!
In a post called "POL and arctan2" from 2005 Nov 14, id w26304 that I wrote you will find an answer.
I was about to try using the arccos() after reading your post but without the Robin's further help I could not get any further.
Hope somebody will compile all those nice tips and tricks about using pocket calculators for AN purposes.
Thank you again.
