Can the minimum be larger than the maximum?

Yes, the tool automatically treats the smaller and larger values as the range bounds regardless of which field you type them into.

What happens if I disallow duplicates but ask for too many numbers?

You'll see a warning and the Generate button is disabled, since your range doesn't contain enough unique numbers to fulfill the request without repeats.

Is this suitable for a real lottery or raffle draw?

It's suitable for casual and low-stakes draws — for regulated or official drawings, check whether your jurisdiction requires a certified random number source.

How many numbers can I generate at once?

Up to 1,000 numbers can be generated in a single batch.

Does "allow duplicates" affect performance?

No, both modes generate instantly — duplicates just means each number is picked independently rather than removed from a shrinking pool.

Can I generate negative numbers?

Yes, enter a negative minimum (or negative maximum) and the range works the same way with negative values included.

Can I copy all the generated numbers at once?

Yes, the copy button copies every generated number as a single comma-separated list.
