Random number generation
All numbers are generated using crypto.getRandomValues(), the Web Crypto API, which provides cryptographically strong randomness. Integer mode generates whole numbers in [min, max]; decimal mode generates floating-point values with up to 10 decimal places. The "Unique" option uses a Fisher-Yates shuffle over the integer range. All generation runs in your browser — nothing is sent anywhere.
Private & free — this tool runs entirely in your browser.
