What Is a Random Number Generator?
A random number generator is a digital tool that creates unpredictable numerical values within specified parameters. Our online random number generator allows you to generate single or multiple random numbers with customizable ranges, decimal precision, and uniqueness constraints.
This tool uses advanced algorithms to ensure true randomness, making it perfect for statistical sampling, gaming applications, lottery simulations, and decision-making processes. You can generate integers or decimal numbers, set custom minimum and maximum values, and choose whether to allow duplicate numbers.
How Do You Use the Random Number Generator?
- Set the Range: Enter your desired minimum and maximum values
- Choose Quantity: Specify how many random numbers you want (1-100)
- Select Precision: Choose decimal places (0 for integers, up to 4)
- Uniqueness Option: Check if you don't want duplicate values
- Click "Generate Numbers" to create your random numbers
- Use "Copy Results" to copy to clipboard

FAQ
How random are the generated numbers?
Our generator uses cryptographically secure pseudorandom number generation algorithms that produce statistically random results suitable for most applications.
Can I generate negative numbers?
Yes! Simply enter a negative value in the minimum number field. You can generate any range including negative numbers.
