Random Number Generator

Generate random numbers in range

Frequently Asked Questions

How does a random number generator work?

A standard computer random number generator uses mathematical algorithms to generate a sequence of numbers that appear random. Because they rely on formulas, they are technically 'pseudo-random' number generators (PRNGs), but they are more than sufficient for games, testing, and statistics.

Can the generator produce unique (non-repeating) numbers?

Yes, our random number generator allows you to choose whether to allow duplicate numbers in your sequence or to generate only unique (non-repeating) numbers within your specified range.

What is a seed in random number generation?

A seed is the starting value used to initialize a pseudo-random number generator. If you initialize the generator with the exact same seed, it will produce the exact same sequence of 'random' numbers, which is useful for debugging code and reproducing scientific experiments.
