Random Number Generator

How it works

1. Set the minimum and maximum values of the range, and how many numbers you want to generate.
2. Turn on "Allow duplicates" if the same number can appear more than once, or turn it off for sampling without repetition.
3. Choose whether you want whole numbers only or decimal values as well.
4. Click "Generate numbers" to get the result, computed with crypto.getRandomValues.
5. Copy the list of results with one click.

Use cases

• Run drawings, raffles, or lotteries by picking winners impartially.
