Frequently Asked Questions

FAQs about Random Number Generator

Are the numbers truly random?

The numbers are generated using Math.random(), a pseudo-random number generator in your browser. For most purposes this is sufficient, but it is not cryptographically secure.

Can the same number appear twice?

Yes. Each number is drawn independently, so duplicates are possible, especially when the range is small relative to the count.

What is the maximum range I can use?

You can use any integer range that fits within JavaScript's safe integer limits (−2^53 to 2^53).

Can I generate negative numbers?

Yes. Set Min to a negative value, for example Min = -50 and Max = 50.

How many numbers can I generate at once?

You can generate up to 1000 numbers in a single click.
