Frequently Asked Questions

What's the difference between unique and non-unique numbers?

When "Unique Numbers" is enabled, each generated number will be different from all others in the set. When disabled, the same number can appear multiple times in your results.

How do decimal numbers work?

When "Include Decimals" is enabled, the generator produces numbers with up to 2 decimal places within your specified range. For example, between 1-10, you might get 3.47, 8.92, etc.

What's the maximum quantity I can generate?

You can generate up to 1,000 numbers at once. For unique numbers, the maximum is limited by your range (e.g., range 1-100 can only produce 100 unique integers).
