Frequently asked questions

Quick answers about ranges, unique results, exclusions, everyday randomness, and privacy.

What can I use the Random Number Generator for?

Use it for everyday number picks, classroom examples, simple games, practice raffles, testing sample values, or choosing a random item from a numbered list.

Can I generate more than one random number?

Yes. Set Quantity to the number of results you want. The generator can create one number or a list of random numbers in the same range.

What do the main Random Number Generator inputs mean?

The main inputs are the everyday values, options, or settings the tool needs before it can help. Read each label literally, keep units consistent, and rerun the example if the answer looks surprising.

How should I read the Random Number Generator answer?

Read the headline answer, then check the smaller lines beside it. For everyday tools, those lines usually show the distance, time, cost, units, or setting that made the answer change.

What should I double-check before trusting the Random Number Generator?

Check units, signs, rounding, and the selected mode before copying the answer. If the number feels weird, rerun one of the examples first, then put your own values back in slowly.

What does unique results mean?

Unique results means the same number will not appear twice in one generated list. If you turn off duplicates, the quantity must fit inside the available range after exclusions.

Can I exclude numbers?

Yes. Enter excluded numbers separated by commas, spaces, or semicolons. Numbers outside the selected range are ignored.

Is this random number generator safe for high-stakes use?

It tries to use browser cryptographic random values when available and maps them into your range without modulo bias. It can fall back to normal browser randomness, so it is still for everyday picks, examples, and practice. Do not use it for passwords, gambling, legal drawings, security decisions, or any process that needs audited randomness.

Is my random number history private?

Yes. Recent random results stay only in the current browser tab while you use the page. They are not sent to a server.
