Random Number Generator
Generate random numbers with customizable range and options.
How to Use
- Set the Minimum and Maximum values for your range.
- Choose how many random numbers to generate.
- Enable or disable duplicates and decimal numbers as needed.
- If decimals are enabled, select the number of decimal places.
- Click Generate to see your random numbers.
- Use Clear Results to reset, or Copy All Numbers to copy the results.
Frequently Asked Questions (FAQ)
Numbers are generated using JavaScript's Math.random() function, which provides pseudo-random values in your browser.
Yes, disable the "Allow duplicate numbers" option to ensure all generated numbers are unique (for integers only).
No. For cryptography, use a dedicated secure random number generator.
No, all calculations are performed locally in your browser. Nothing is sent or stored externally.
Understanding Random Numbers
Random numbers are used in games, simulations, statistics, and more. They are essential for sampling, shuffling, and creating unpredictable outcomes.
Limitations:
- JavaScript's random numbers are not truly random, but pseudo-random.
- Not suitable for security-critical or cryptographic applications.
- Results may repeat if duplicates are allowed or if the range is small.
This tool is for general use and should not be relied on for high-stakes randomness.
