How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Specify a range and how many numbers to generate (up to 10). Each calculation produces a fresh set of random integers using JavaScript's Math.random(). Results change each time you calculate.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

Are the numbers truly random?

They use Math.random(), which is a pseudo-random number generator. It is sufficient for games, selections, and simulations but not for cryptography.

Can I get duplicates?

Yes. The generator samples independently each time, so duplicates are possible especially in small ranges.
