Perguntas Frequentes
Are the numbers truly random?
The numbers are generated using JavaScript's Math.random() function, which produces pseudo-random numbers with uniform distribution. While not cryptographically secure, they are more than sufficient for games, sampling, testing, and general-purpose randomness needs.
What's the maximum range?
You can set any minimum and maximum values within JavaScript's safe integer range. This allows you to generate random numbers from very small to very large ranges, covering virtually any use case from simple dice rolls to large-scale number generation.
Is this tool free?
Yes, the random number generator is completely free to use with no registration required. There are no usage limits or hidden costs. Generate as many random numbers as you need for lottery picks, games, research, or any other purpose.
