Frequently Asked Questions
Is this truly random?
Yes. We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure pseudo-random numbers. This is the same standard used by security applications and is far superior to Math.random() for randomness quality.
Can I generate multiple numbers at once?
Yes! Set the 'Count' field to generate up to 100 random numbers in a single batch. You can also toggle 'Unique only' to ensure no duplicates in your batch (when the range is large enough).
What are common uses for random numbers?
Random numbers are used for: lottery/raffle draws, game mechanics, statistical sampling, password generation, choosing random items from a list, educational exercises, and decision making.
Can I set decimal precision?
Currently the generator produces whole integers. For decimal numbers, you can generate a larger range and divide the result (e.g., generate 0-1000 and divide by 100 for 2 decimal places).
