❓ Frequently Asked Questions
How random are the generated numbers?
Our generator uses JavaScript's crypto.getRandomValues() when available, which provides cryptographically secure random numbers. This is suitable for most applications including security-sensitive ones.
Can I generate numbers with specific distributions?
This tool generates numbers with uniform distribution. For other distributions (normal, exponential, etc.), the numbers can be used as a base for mathematical transformations.
What's the maximum range I can use?
You can use any range that fits within JavaScript's number limits (approximately ±1.8 × 10^308). Very large ranges work fine for most practical applications.
Why would I want unique numbers vs duplicates?
Unique numbers are useful for sampling, lottery draws, or selecting distinct items. Duplicates are fine for simulations, gaming, or when each generation is independent.
Can I use this for password generation?
While you can generate random numbers for passwords, consider using our dedicated Password Generator tool which creates more secure, mixed-character passwords.
How do I get reproducible results?
True random numbers aren't reproducible by design. If you need reproducible sequences, consider using a pseudorandom number generator with a known seed value.
