Montecarlo method of pi calculation

Montecarlo method of pi calculation. No loops!!!

A circle of radius 0.5 is inscribed inside a square with side length 1.
Script picks N points at random inside the square. It then checks to see if the point is inside the circle and then generates a figure in which the points ''in'' and ''out'' are plotted in different colors. Say we have M points inside the circle. Pi is then approximated as follows:
% Pi = 4*M/N.
