Can I generate numbers without duplicates?

Yes. Tick the No duplicate numbers box and every draw will be distinct, as long as the range contains enough values for the count you requested.

How many random numbers can I generate at once?

Between 1 and 1,000 per click, and you can generate as many batches as you like. The last eight batches are shown in the history section.

Can the generator produce decimal numbers?

Yes. Set the decimal places field anywhere from 0 to 10. At 0 you get whole numbers; above 0 the draws are rounded to that precision.

Can I exclude certain numbers?

Yes. Type a comma-separated list into the Exclude numbers field, for example 13, 27, 42, and any draw that lands on a listed value is skipped and retried.

Is this generator safe for passwords or security tokens?

No. It uses the pseudo-random Math.random source, which is not cryptographically secure. For passwords, tokens or anything security-related, use a dedicated secure generator.

Why does the tool sometimes refuse to generate?

It validates your settings first: the minimum must be below the maximum, the count must be between 1 and 1,000, decimals between 0 and 10, and unique draws must be mathematically possible in the chosen range.

Can I copy the result?

Yes. The Copy button places the latest result on your clipboard. Results with multiple numbers are copied as a comma-separated list.

Is my data sent to a server?

No. All generation happens locally in your browser using JavaScript. Nothing you enter is uploaded, stored or logged.

Does the tool support sorting?

Yes. Tick Sort results ascending to have the drawn numbers ordered from lowest to highest before display. Note that sorting changes the order from the draw sequence.

Can I exclude specific numbers or get a list of unique numbers?

Yes. The generator can produce multiple numbers at once and supports unique-number mode, which draws each value from the range only once. This is ideal for lotteries, brackets and ordered draws where repeats would be invalid.
