Frequently Asked Questions
A random number generator (RNG) is a tool that produces unpredictable numbers within a specified range. It uses algorithms to generate numbers that have no discernible pattern, making each number equally likely to appear.
Random numbers are useful for: lottery and raffle drawings, picking random winners from a list, generating test data, statistical sampling, creating game mechanics, random selection for surveys, and any situation requiring unbiased selection.
Yes! Our generator supports multiple number systems: Decimal (base 10) for standard numbers, Hexadecimal (base 16) for programming and colors, Octal (base 8), and Binary (base 2) for computer science applications.
You can generate up to 100,000 random numbers in a single request. You can also choose to display them in multiple columns (up to 10) for easier reading.
Our random number generator uses JavaScript's Math.random() function, which provides pseudorandom numbers suitable for most applications including games, simulations, and fair selections. For cryptographic purposes, a hardware random number generator would be recommended.
