Frequently asked questions
How random is this generator?
It uses the Web Crypto API's crypto.getRandomValues, which produces cryptographically strong random numbers. That is far stronger than the Math.random() used by basic generators.
What is the maximum range?
Integers can span the full safe integer range, roughly negative to positive 9 quadrillion. Decimals are limited by JavaScript's double precision, about 15 significant digits.
Can I generate non-repeating numbers for a raffle?
Yes. Enable the Unique toggle and the generator returns distinct values in your range. Note that the number of unique values requested cannot exceed the size of the range.
Are the numbers seeded?
No. Each generation is fresh and unpredictable because the cryptographic random source has no observable seed.
