   I don't follow.  What is "my" n?  I did not mention an n.   
      
   I don't see why the problem can't be naturally extended to a circular   
   real interval [0, 1), subject to the fact that we'll use floating point   
   numbers for practical purposes.  But I don't think this is what you were   
   talking about.
