Try a range of 1 to 99999. It is interesting to see how often the numbers are very large, most of them are equal to or one digit less than the top of the range. Why would this be? If you enter a range of 1 to 2, does this become like flipping a coin? Do you change from a random output to a more predictable chance output with smaller and smaller ranges? |

Errr. There are 9 times more 5 digit numbers then there are 4, 3, 2, and 1 digit numbers combined, so what would you expect? Most numbers randomly selected will have five digits.
I wonder how they can certify that it is truly random... is it hooked up to a quantum computer?

Nothing is really totally random on this scale, but it uses atmospheric turbulence or something like that. Similar to snow on a TV screen, I think it is pretty good. One could take down 100 of the numbers and check it out, but I bet it is fairly random, provided you select a large enough range to be safe. I dont think 1 to 10 is good enough for the most demanding applications.
Yes I do understand why the large numbers come up more often, jerk sauce, I was just interested to see it anyway. You still expect to see some low numbers in there, but no matter how much you click the odds of getting a double digit number is pretty low. Let alone single.

Post another hot AZN and I'll show you jerk sauce.
