Frequently Asked Questions

Our generator uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. This ensures the numbers are truly unpredictable and suitable for any application requiring randomness.
Integers are whole numbers (1, 2, 3) while decimals include fractional parts (1.5, 2.75, 3.142). Choose integers for counting, lottery numbers, or dice-like results. Choose decimals for scientific calculations, percentages, or continuous ranges.
Yes! Disable "Allow Duplicates" to ensure each number appears only once. Note: the quantity cannot exceed the range when duplicates are disabled. For example, you can only generate 10 unique numbers between 1-10.
Currently we support uniform distribution where every number in the range has equal probability. This is ideal for fair random selection. Future updates may include normal (Gaussian) distribution for bell-curve results.
Set your min to 1, max to the highest lottery number (e.g., 69 for Powerball), quantity to the number of balls drawn (e.g., 5), and disable duplicates. This gives you unique random numbers within the lottery range.
