Guide
How to use this tool
- 1
Set the range limits
Enter the minimum and maximum values between which numbers may be generated.
- 2
Choose the draw settings
Select the quantity, integer or decimal mode, and whether values must be unique.
- 3
Generate and review the values
Run the generator and confirm that the results match the constraints you selected.
Tips and best practices
- Enable unique values only when the selected range contains enough possible results for the requested quantity.
- For decimals, choose a range that produces meaningful values for your test or simulation.
- Do not use this generator for keys, security tokens, passwords, or other cryptographic purposes.
Frequently asked questions
Can generated numbers contain duplicates?
Yes, unless unique values are enabled and the range is large enough to provide the requested number of distinct results.
Can I generate decimal numbers?
Yes. Disable integer mode when you want decimal values.
Is this generator suitable for cryptography?
No. It is intended for everyday use and should not be used to generate secrets or security-sensitive values.
Does generation require a remote server?
No. Numbers are generated directly in your browser.
