Random Number Generator FAQs
Common questions about generating random numbers
How random are the generated numbers?
The numbers are generated using JavaScript's Math.random(), which uses a pseudo-random number generator. While not cryptographically secure, it provides sufficient randomness for most applications like games, testing, and simulations.
Can I generate negative numbers?
Yes, you can set negative values for the minimum or maximum range. The generator will produce random numbers within the specified range, including negative values.
Are the numbers truly random?
The numbers are pseudo-random, meaning they are generated by an algorithm that produces sequences that appear random. For cryptographic purposes, you would need a cryptographically secure random number generator.
What is the maximum range I can use?
JavaScript can handle very large numbers, but for practical purposes, the range is limited by JavaScript's number precision. The tool supports ranges from -1000 to 1000 by default, but you can manually enter any valid number range.
Is my data sent to a server?
No, all number generation is performed client-side in your browser. Your range preferences and generated numbers are not sent to any server, ensuring privacy and security.
Can I generate multiple numbers at once?
Currently, the tool generates one number at a time. You can click "Generate Random Number" multiple times to generate different numbers within your specified range.
How do I ensure uniform distribution?
The generator uses Math.floor(Math.random() * (max - min + 1)) + min, which ensures each number in the range has an equal probability of being selected, providing a uniform distribution.
