Abstract

In this work, we develop a new iterative method for computing the digits of π\pi by argument reduction of the tangent function. This method combines a modified version of the iterative formula for π\pi with squared convergence that we proposed in a previous work and a leading arctangent term from the Machin-like formula. The computational test we performed shows that algorithmic implementation can provide more than 1717 digits of π\pi per increment. Mathematica codes, showing the convergence rate for computing the digits of π\pi, are presented.
