Frequently Asked Questions
How random are the generated numbers?
Our random number generator uses cryptographically secure randomization (Web Crypto API), the same technology used in encryption and security applications. This ensures truly random, unpredictable numbers with uniform distribution across your specified range.
Can I use this for lottery number selection?
Yes! Many people use our generator to pick lottery numbers. Set the range to match your lottery (e.g., 1-69 for Powerball), generate the needed amount of numbers, and you'll get fair, random selections every time.
What's the maximum range I can use?
You can generate random numbers in any range from negative to positive integers. Whether you need numbers between 1-10 or 1-1,000,000, our generator handles it all with the same level of security and randomness.
Is this suitable for research or statistical analysis?
Absolutely! Our cryptographically secure random number generation is suitable for academic research, statistical sampling, Monte Carlo simulations, and other applications requiring high-quality randomness. The uniform distribution ensures statistically valid results.
Does it work offline?
Our random number generator requires an initial page load but uses your browser's built-in Web Crypto API for number generation. Once loaded, it generates numbers locally in your browser without sending data to our servers.
How is this different from Excel's RAND() or Google Sheets?
While Excel and Google Sheets use pseudo-random algorithms, our generator uses cryptographically secure randomization for higher quality randomness. It's also more convenient - no spreadsheet setup needed, works on any device, and provides a cleaner interface for quick number generation.
