How to use the random number generator

Enter an inclusive minimum and maximum, then choose how many whole numbers to generate. Use the Generate again button whenever you want a new set.

Random integer range

Calculation formulaRandom integer range
Used for the result above
Result = floor(random × (max − min + 1)) + min.

This tool uses the browser's cryptographically secure random values when available rather than Math.random().

Example: Mia selects a practice question

Mia has 10 numbered practice questions. With a minimum of 1, maximum of 10, and quantity of 1, the generator can return any integer from 1 through 10, including both endpoints.

If she requests several numbers, repeats are allowed. This is useful for informal choices and practice; it is not a password generator or an audited prize-draw system.

Check the range before generating

With a minimum of 1 and maximum of 6, every result is a whole number from 1 through 6. Both endpoints are included.

Each draw is independent, so numbers can repeat when you request several results. This tool does not provide a no-repeat draw or a security key.

Repeated results are a normal outcome

A single draw from 1 through 6 has six possible outcomes. Requesting six results does not guarantee one of each number because each draw is independent and repeats are allowed.

For example, 2, 2, 5 is a possible three-number result. For a selection without repeats, you need a tool that samples without replacement. This generator is intended for everyday choices and practice tasks.

What the estimate assumes

This tool is not certified for regulated gaming, lotteries, security key generation, or scientific randomization protocols.

Random Number Generator FAQs

Are the minimum and maximum included?

Yes.

Can numbers repeat?

Yes. Each generated number is independent, so duplicates are possible when quantity is greater than one.

Can I use negative numbers?

Yes.

Is this suitable for passwords or cryptographic keys?

No. Use a purpose-built security tool for cryptographic secrets.

General-purpose random-number tool. Do not use it where certified or auditable randomness is required.
