Free Online Text Random Number Generator
What Is a Random Number Generator?
A random number generator (RNG) is a mathematical tool that produces a sequence of numbers that lack any predictable pattern. Our free online random number generator allows you to create random numbers within any range you specify, with options for unique values and sorting.
How to Use Our Random Number Generator
Using our tool is simple:
- Enter your minimum and maximum values (e.g., 1 to 100)
- Select how many random numbers you need
- Choose options like unique numbers or sorting
- Click "Generate Random Numbers"
- Copy your results or generate new numbers
Common Uses for Random Numbers
Random numbers have many practical applications:
- Lotteries and prize draws: Fairly select winners without bias
- Statistical sampling: Create representative samples for research
- Games and simulations: Generate unpredictable outcomes
- Password generation: Create secure, hard-to-guess codes
- Educational purposes: Teach probability and statistics concepts
How Random Number Generators Work
Our tool uses JavaScript's Math.random() function combined with the Fisher-Yates shuffle algorithm to produce high-quality pseudo-random numbers. While not truly random (as they're generated by algorithms), these numbers are statistically random for most practical purposes.
Frequently Asked Questions
Can I generate negative random numbers?
Yes! Simply set your minimum value to a negative number (e.g., -100 to 100).
How many numbers can I generate at once?
Our generator allows up to 1,000 numbers at a time. For unique numbers, your range must be larger than the quantity requested.
Are the numbers truly random?
They are pseudo-random, meaning they're generated by an algorithm but appear random for most applications. For cryptographic purposes, specialized hardware generators are recommended.
