%N Number of nontrivial zeros of the Riemann Zeta function in the interval 1/2+i[n,n+1).

%C It gives the number of zeros for each integer.

%C The average value is a(n) ~ log(n)/(2*Pi).

%e First zero is at 14.134, therefore a(14) = 1, the second is at 21.022 therefore a(21) = 1, there are 2 zeros between 111 and 112, a(111) = 2.
