Frequently Asked Questions
How does this random number generator guarantee fair, cryptographically secure results?
Numbers are generated using the Web Cryptography API (crypto.getRandomValues) with unbiased rejection sampling, eliminating the statistical clustering and predictable seeds inherent in standard software random generators.
Can I generate unique non-repeating numbers for lotteries and raffles?
Yes. You can toggle the 'Allow Duplicates' switch off to generate strictly unique, non-repeating integers within your selected minimum and maximum boundaries.
Can I generate decimal fractions and sort the output automatically?
Yes. The generator supports decimal numbers up to 6 decimal places, ascending or descending sorting, custom delimiters, and one-click clipboard copying.
