What this calculator does
Use this random number generator to pick whole numbers from a range. The seed makes the same inputs produce the same list, which is useful when you need a result you can reproduce.
Formula used
The calculator uses a simple deterministic number generator based on the seed, then maps each generated value into the requested range.
How to read the result
Change the seed to get a different list. This is suitable for everyday choices and examples, not cryptography or regulated draws.
Assumptions
- Generates whole numbers only.
- Numbers may repeat.
- Not suitable for security-sensitive random numbers.
Sources and checks
This calculator uses a standard public formula. Where rules or thresholds can change, source links are listed on the relevant page.
Frequently asked questions
Why is there a seed?
A seed makes the result repeatable. That avoids surprising page loads while still letting you generate a new list by changing the seed.
