Frequently asked questions
Are the numbers truly random?
This tool uses your browser's built-in cryptographic random number generator (crypto.getRandomValues), which provides high-quality randomness suitable for most purposes.
Can I generate decimal numbers?
This depends on the tool settings. Many generators produce integers only by default — check if there is a decimal option if you need fractional values.
