Pi-Calculation How to calculate a pi 1. Choose x and y values at random between 0 and 1.- 2.Make sure (x y) points are centered around their origin and have a radius of one 3.after several iterations of the process 1 through 2, if the number of points in a circle is k, and the total number of points selected is n,. the value of k has the value of pi /4. 4.Multiply the value obtained from 3 by 4 and you get the pi.. - Print intermediate calculation results with a repeat count of 1000000 times for the previously introduced Pi-computing method, and output the time spent on the calculation after the calculation..
