Frequently asked questions (FAQ)
🔹 How fair is this randomizer?
The generator uses a pseudo-random number algorithm (Math.random) built into the browser. This ensures a uniform probability distribution sufficient for any everyday and competitive problems.
🔹 Is it possible to generate negative numbers?
Yes. You can enter a minus before the number (for example, -100 to 100). The system will process this range correctly.
🔹 What should I do if I mixed up the minimum and maximum?
No problem. Our script will automatically determine which number is greater and which is less, and will produce the correct result in the required interval.
