About the Random Number Generator
This tool generates random integers using JavaScript's built-in Math.random() function. You can use it for games, lotteries, raffles, testing, or any situation where you need unpredictable results.
How It Works
The algorithm used here follows a basic method of generating pseudo-random numbers between a minimum and maximum value. While not suitable for cryptographic purposes, it works well for general use cases like selecting contest winners or simulating dice rolls.
Key Features
- Specify minimum and maximum values
- Generate multiple random numbers at once
- See instant results in an organized list
- Clear all inputs and results with one click
How to Use
- Enter the minimum value for your range
- Enter the maximum value for your range
- Optionally specify how many numbers you want
- Click "Generate Numbers"
Example Uses
- Selecting contest winners fairly
- Simulating dice rolls or card draws
- Generating sample data for testing
- Choosing random names or items from a list
- Creating unique identifiers or codes
Frequently Asked Questions
Is this a true random number generator?
No, this is a pseudo-random number generator based on JavaScript's Math.random() function. For most practical purposes, the results appear random, but they are generated by a deterministic algorithm and should not be used for security-sensitive applications.
Can I get duplicate numbers?
Yes, duplicates are possible when generating multiple numbers because each number is generated independently. If you need unique numbers without repetition, consider using a shuffle algorithm instead.
What range of numbers can I generate?
You can generate numbers across a wide range, including negative values. The only requirement is that the minimum value must be less than or equal to the maximum value.
Are there limits on how many numbers I can generate?
There is no strict limit, but generating extremely large quantities of numbers (thousands or more) may affect performance. For most typical uses (up to 100 numbers), performance will be smooth and instantaneous.
Can I use this tool on mobile devices?
Yes! This tool is fully responsive and works great on smartphones, tablets, and desktop computers alike. Just open it in any modern web browser.
