%C A024584 From _Hieronymus Fischer_, Apr 15 2012: (Start)
%C A024584 The sequence is well defined, since frac(n*Pi)>0 for n>0.
%C A024584 Let b(n,m)=|{a(k)| 1<=k<=n, a(k)>=m}| be the number of the first n terms which are >= m >= 1.
%C A024584 Then, lim b(n,m)/n = 1/m for n-->oo since frac(n*pi) is uniformly distributed. (End)
