%N A115789 (Floor((n+1)*pi)-Floor(n*pi)) mod 2.
%C A115789 The arithmetic mean 1/(n+1)*sum(a(k)|k=0...n) converges to 4-pi. What 
               is effectively the same: the Cesaro limit (C1) of a(n) is 4-pi.
%F A115789 a(n) = (Floor((n+1)*pi)-Floor(n*pi)) mod 2.
%e A115789 a(6)=1 because 7*pi=21.99, 6*pi=18.85 and so a(6)=(21-18) mod 2 = 1;
%e A115789 a(7)=0 because 8*pi=25.13 and so a(7)=(25-21) mod 2 = 0;
