Frequently Asked Questions

How random are these numbers?

The numbers are generated using JavaScript's Math.random() function, which provides pseudo-random numbers suitable for most purposes including games, raffles, and testing. For cryptographic purposes, use specialized cryptographic random number generators.

What is the difference between allowing and preventing duplicates?

When duplicates are allowed, the same number can appear multiple times in the results. When duplicates are prevented, each number will be unique. Note that you cannot generate more unique numbers than the range allows.

Can I generate negative numbers?

Yes! You can use negative numbers for both minimum and maximum values. For example, you can generate numbers between -100 and 100.

What is the maximum range I can use?

There's no strict limit on the range, but very large ranges (billions or more) may affect performance. For practical purposes, any reasonable range will work instantly.

Can I use this for lottery numbers?

Yes! This tool is perfect for generating lottery numbers. Set your range (e.g., 1-49), specify how many numbers you need, and disable duplicates to ensure unique numbers.
