Information about random number generation
The random number generator creates completely random numbers within your specified range. It can be used for raffles, chance games, statistical sampling, and decision-making processes. If you allow duplicates, the same number can appear multiple times. In non-duplicate mode, each number is generated at most once. Example use cases: Lottery numbers, team selection, order determination, random selection, password generation, game dice, and test data generation. Note: This tool is not cryptographically secure and should not be used in security-critical applications.
Find answers to common questions
The random number generator uses JavaScript's Math.random() function to generate a random number between 0 and 1, then scales it to your specified range. For example, for 1-100, it uses the formula Math.floor(Math.random() * 100) + 1.
