Calculating pi
@mikrom: yeah you're right, I noticed that! In my opinion the fact that with n = 4678343 we get a better result than with n = 2147483647 could be possibly due to the fact that also in this plot http://upload.wikimedia.org/wikipedia/commons/7/7d/Errore_montecarlo_calcolo_pi_greco.PNG the error... -
Calculating pi
@mikrom: you're right! call random_number works better than rand(), even though the convergence is very slow. I found this picture on Wikipedia that shows the percent error as a function of the number of drops, and it says that overall the program generated 1,37 billion drops, which is similar... -

Calculating pi
@mikrom: and how could you do that? In fact, in another situation as well I needed a number bigger than 2^31-1, but I didn't manage to solve it. Is there any way? -
Calculating pi
Whoa thank you very much! Both of your answers were very helpful! Thanks for the code, it's really useful to see another way to answer the problem. And I didn't know I wasn't using double precision numbers for all my values. You've just opened a new world for me! Thank you. -

Calculating pi
Hello everyone, I'm trying to calculate pi by following an idea on Wikipedia http://en.wikipedia.org/wiki/Monte_Carlo_method In practice I generate some random points (x,y) in a square (side=1) and counting how many points are in the square and how many are in the circle (radius=1) remembering...
