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.

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.

What this random number generator does

The tool generates whole numbers between the minimum and maximum values you enter, including the endpoints when they are selected. Use it for casual selections, games, classroom activities, test data, or other low-stakes tasks.

Generating again creates a new pseudorandom result from the browser environment. The previous result is not used to influence the next one.

Pseudorandom is not the same as certified randomness

General browser-based randomness is suitable for ordinary utility use, but it should not be treated as a certified drawing system, cryptographic key generator, regulated gambling tool, or auditable lottery mechanism.

High-stakes security and regulated selections require purpose-built randomness sources, controls, and audit procedures beyond this page.

Assumptions and limitations

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.

Can I use this for a lottery or security key?

No. It is designed for ordinary utility use, not certified drawings, gambling systems, cryptographic secrets, or other high-stakes randomness.

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