A193496 a(n) = 1 iff digit n+1 of Pi is >= digit n, otherwise a(n) = 0. We consider 3 to be digit 1 of Pi.

Index entries for sequences related to the number Pi

Formula

If A000796(n+1) >= A000796(n) then a(n)=1, otherwise a(n)=0.

a(n) = if A095916(n) < 0 then 0, otherwise 1. - Reinhard Zumkeller, Mar 12 2015

Example

a(1) = 0 because A000796(2)=1 < A000796(1)=3.

Mathematica

nn = 100; d = RealDigits[N[Pi, nn]][[1]]; Table[Boole[d[[n + 1]] >= d[[n]]], {n, nn - 1}] (* T. D. Noe, Jul 29 2011 *)
