% Function piTiling % Eric Young / CS 100 M % function piApproximation = piTiling(n,f); f % Estimates the value of pi by tiling a circle of known radius n. % Pi is approximated as the number of cut + uncut tiles in the circle % divided by the radius, n, squared. % n is an integer radius of the circle to be tiled % f is the fraction of a tile assumed for any cut tile % % Tile the first quadrant, later multiply by four % N_uncut = 0;
