What Is a Random Number Generator?

A random number generator (RNG) is a tool that produces numbers in a random sequence within a specified range. This calculator uses a pseudo-random number generator (PRNG), which generates numbers that appear random but are determined by an algorithm. PRNGs are suitable for most general purposes but not for cryptographic applications requiring true randomness.

How to Use This Calculator

Follow these steps to generate random numbers:

• Enter the Range: Specify the minimum and maximum values for the range.
• Specify Quantity: Enter how many numbers you want to generate (1 to 100).
• Choose Type: Select whether to generate integers or decimals.
• Set Precision (for Decimals): If generating decimals, specify the number of decimal places (0 to 10).
• Generate: Click the "Generate" button to see the results.
• Clear: Use the "Clear" button to reset the form.

Common Uses of Random Numbers

Random numbers have a wide range of applications:

• Gaming: Generate dice rolls, card shuffles, or random events in games.
• Statistics: Use random sampling for experiments or simulations.
• Education: Create practice problems or quizzes with random values.
• Decision Making: Make random selections, such as picking a winner in a raffle.

Limitations of Pseudo-Random Numbers

While this calculator is useful for general purposes, it has limitations:

• Not Truly Random: The numbers are generated by an algorithm and are not suitable for cryptographic purposes.
• Possible Duplicates: The generator does not prevent duplicates, as each number is generated independently.
• Range Limitations: Extremely large ranges may lead to performance issues due to JavaScript limitations.
