How This Random Number Generator Works
This tool uses your browser's built-in pseudo-random number generator to pick numbers uniformly across your chosen range, then scales and rounds the result to fit your minimum, maximum, and decimal precision.
No duplicates mode removes each number from the pool once it's drawn, so you'll never see the same value twice in one batch, useful for raffles or drawing names.
Note: this generator is suitable for games, samples, and everyday randomness, but it is not cryptographically secure and shouldn't be used for security keys, passwords, or gambling systems that require certified randomness.
How to Use This Random Number Generator
Set your minimum and maximum range.
Choose how many numbers you want, and whether duplicates are allowed.

Frequently Asked Questions
Is this generator truly random?
It uses your browser's pseudo-random number generator, which is random enough for everyday use like games, raffles, and sampling, but not certified for cryptographic or gambling applications.
Can I generate numbers without duplicates?
Yes, check "No duplicates" and each number will only appear once per batch. Note that the count can't exceed the number of values available in your chosen range.
Can I generate decimal numbers, not just whole numbers?
Yes, set "Decimal places" to any value above 0 to generate numbers with that many digits after the decimal point.
Is there a limit to how many numbers I can generate?
You can generate as many as you like, though very large batches with "no duplicates" enabled are limited by the size of your selected range.
