The RANDI_ORG function has a similar usage as the RANDI function. However, instead of returning pseudo-random numbers, it queries the site http://www.random.org to collect true random numbers. Refer to the web site for a discussion on the difference between pseudo and true randomness.

Note that http://www.random.org allows limited traffic per day, check the site for more details.
