About this tool: Random Number Generator
Generate local random integers between chosen limits using browser cryptographic randomness and reject impossible unique-value requests.
Use it to compare scenarios quickly while keeping the relevant values, units, dates or rates visible on one page.
Random Number Generator is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
Random integers are generated locally using crypto.getRandomValues with rejection sampling to avoid modulo bias.
Practical example
Range 1–10 with quantity 3 returns three locally generated integers; results vary each run.
Important notes
Check the entered units, dates, decimal placement and any assumptions before relying on the result.
Privacy & processing
The calculation is performed in the browser from the values you enter.
Frequently asked questions
What does Random Number Generator do?
