>>13844641e ^ (i * (distance covered on the unit circle, given that you have started at (1, 0) and moved counterclockwise at unit speed))
= the coordinates of that circle
So, if you moved distance equal to half of the perimeter of the unit circle (i.e. ?), you end up at the point (-1, 0) which is the complex number -1.
If you cover distance 180, then you end up at the same point as if you covered distance 180 mod (2*pi) = 0.9292 which has coordinates (-0.5984, 0.8012)
