Frequently asked questions
Are the numbers truly random?
They come from the browser's pseudo-random generator. That is fine for draws, games and sampling, but not for cryptographic keys.
Are the bounds included?
Yes. Both the minimum and the maximum can come up, so a range of 1 to 10 can produce 1 and 10.
Why can I not get unique numbers?
Because you asked for more numbers than the range contains. A range of 1 to 5 cannot yield ten different values.
