Practical guide
How to use the number generator
The number generator returns a pseudo-random integer within the selected minimum and maximum. It is useful for ordinary choices and test data, but it is not intended for lotteries, cryptographic keys or regulated drawings.
Good reasons to use it
- Select a random item index for a casual choice.
- Generate varied test values within a known range.
- Demonstrate inclusive minimum and maximum boundaries.
A reliable workflow
- Enter an integer minimum and maximum.
- Generate a result.
- Use a cryptographically secure or audited method when fairness or security matters.
How to interpret the result
Each valid number in the range should be possible, but a short sequence does not need to look evenly distributed. Pseudo-random output depends on the implementation and environment.
Frequently asked questions
Are the endpoints included?
Yes, the selected minimum and maximum are eligible results.
Why can the same number appear twice?
Independent random draws can repeat. Uniqueness requires sampling without replacement.
