Common Questions
Are the 'Min' and 'Max' values included?
Yes. Both boundary numbers are included in the pool of possible results (Inclusive Range).
Can numbers repeat?
Yes. Each click is an independent event, meaning it's possible for the same number to appear again purely by chance.
Does it support decimal numbers?
This specific tool is optimized for 'Whole Numbers' (Integers), which are most commonly needed for draws and games.
What is the largest range I can use?
The tool can handle ranges spanning trillions, limited only by standard JavaScript numeric constraints.
Is it safe for picking passwords?
It is great for inspiration, but for high-security applications, always use a dedicated cryptographic key generator.
