Frequently Asked Questions
This tool generates numbers directly in your browser. It lets you control the minimum and maximum range, quantity, integer or decimal mode, duplicate handling, sorting, excluded values, and optional seeds for repeatable output.
Yes. Turn off repeats and the generator will avoid duplicate values. If your requested amount is larger than the available range after exclusions, the tool will prompt you to widen the range or reduce the count.
Yes. Switch to decimal mode, choose the number of decimal places, and the tool will generate values aligned to that precision between your minimum and maximum range.
A seed makes the output reproducible. Using the same seed with the same settings produces the same sequence again, which is useful for testing, game logic, and classroom demos.
No. The generator runs locally in the browser, and your recent history is stored only on your device for convenience.
