Random Number Generator

This tool uses Math.random() which is a pseudorandom number generator (PRNG) — sufficient for most uses like games, sampling, and simulations. For cryptographic security, use the UUID Generator which uses crypto.getRandomValues().

Yes — enable the "No duplicates" option. The tool will ensure each number appears at most once. If count exceeds the number of unique integers in the range, it will automatically cap at the maximum unique count possible.

Yes — set "Decimal places" to any number from 1 to 10. For example, min=0, max=1 with 2 decimal places generates values like 0.37, 0.91, etc. For integers, keep decimal places at 0.
