arrow length problem with 'quiver' function

I want to plot arrows using 'quiver' function along a circle, the circle is within a very small radius: ~0.02
the problem is that, the velocity is very large: over 20 m/s, and I need to use the scale factor to control its length. I read through the documents of 'quiver' function:
it mentioned that, while using factor 2, the length doubles, while using factor 0.5, the length becomes half. in this logic, it should be the original length when using factor 1, but, in the documentation, the length become orginal length when using factor 0.
so my question is that, what is the logic behind this factor? I do not find it anywhere.
I also add test data, please see attached, the command is:
quiver(cylx,cyly,vx,vy)
Thanks!

The quiver function has more options that what is listed in the examples of the quiver function documentation.
