What does this generator do?
It produces truly arbitrary numbers within any range you choose. Generate a single number or up to 100 at once, as integers or decimals (with 0–10 decimal places), and decide whether repeats are allowed — turn them off for lottery-style draws where every number must be unique.
Common uses
- Draws and giveaways — pick winning entries without bias.
- Games and teaching — dice rolls, quiz order, random grouping.
- Development and testing — quick sample data in a specific range.
How to use it
- Set how many numbers you need and the min/max range.
- Choose integer or decimal (and precision for decimals).
- Untick Allow repeated numbers if every result must be unique.
- Hit Generate — copy or download the results.
Note: numbers come from your browser's pseudo-random generator. That's perfect for games, sampling and testing, but for cryptographic purposes use a dedicated secure generator.
