201–219. In number theory, a branch of mathematics, Ramanujan's sum, usually denoted c q (n), is a function of two positive integer variables q and n defined by the formula: = ∑ ≤ ≤ (,) =,where (a, q) = 1 means that a only takes on values coprime to q.Srinivasa Ramanujan mentioned the sums in a 1918 paper. In addition to the expansions discussed in this article, Ramanujan's sums are used in the

We show that computation and verification of $$\pi $$ using the two different BBP-type formulas require 20% fewer terms than verification by shifting the starting position of a few hexadecimal digits of $$\pi $$ using Huvent’s formula, which is known as the BBP-type formula with the least number of terms.
