Frequently Asked Questions
What is a random number generator?
A random number generator (RNG) is a computational device designed to generate a sequence of numbers that lack any pattern, i.e., appear random. Our tool lets you generate random numbers within a specified range, with or without duplicates.
How do online random number generators work?
Online random number generators typically use algorithms called pseudo-random number generators (PRNGs). These algorithms start with a seed value and apply mathematical formulas to produce numbers that appear random. True randomness in computers is difficult to achieve without external entropy sources.
Are online random generators truly random?
Online random generators like this one use pseudo-random algorithms which produce sequences that appear random but are actually deterministic. They're sufficiently random for most common purposes like games or simulations, but may not be suitable for cryptographic applications or scientific research requiring true randomness.
What can I use a random number generator for?
Random number generators have many uses including selecting lottery numbers, creating random samples for statistical analysis, simulating dice rolls for board games, making random selections from a list, creating random passwords, conducting fair raffles or giveaways, and randomizing the order of items or people.
