nevertheless, output here is different, as I described
Wait, I missed an unexpected minus sign on a different line.
Yes, the result is different, because [cyclone/cartopol~] does this instead :
[expr~ hypot($v1,-$v2) ; atan2(-$v2,$v1)].
For hypot, sign and order of args does not matter, but for atan2, they do.
