Frequently Asked Questions
How are the random numbers generated?
This tool uses crypto.getRandomValues(), a cryptographically secure random number generator built into modern browsers. It provides true randomness, not pseudo-random.
Can I generate decimal numbers?
Yes. Set the decimal places option between 1 and 4 to generate decimal numbers with fractional parts.
What does "Unique" mode do?
When Unique is enabled, all generated numbers will be different. If the range is too small to produce the requested count of unique numbers, an error message will appear.
