Frequently Asked Questions
Are the numbers truly random?
Yes. The generator uses JavaScript's Math.random(), which is seeded by the browser's built-in entropy source — producing high-quality pseudorandom numbers suitable for most everyday use cases.
What is the maximum quantity I can generate?
You can generate up to 10,000 numbers in one click. For unique integers, the quantity cannot exceed the size of your chosen range.
Can I generate negative numbers?
Yes. Simply set Min to a negative value (e.g. -100) and Max to any number greater than Min.
