Random Number Generator
Generate random numbers online in seconds. Choose a range, pick random integers or random decimals, set how many values you need, allow duplicates or force unique results, then sort and copy your list.
Built for everyday use: games, classroom activities, sampling, and quick test data. Not for cryptographic security.
Build your random number list
Enter a range, choose integer or decimal output (0 to 8 places), and decide how many random numbers you want. Integer ranges are inclusive.
Recommended: 1 to 100 numbers per batch.
Unique results are limited by the range size and decimal precision.
Results
Copy results as a comma-separated list for spreadsheets, notes, or quick reuse.
Set a range and click Generate Random Numbers to see your list.
What this random number generator does
This tool generates random numbers within a custom range. You can create a short list or a larger batch, choose integer or decimal output, allow duplicates, and sort results for easy use.
Custom range
Set a minimum and maximum value. Integer ranges include both ends.
Integer or decimal
Generate random integers or decimals with 0 to 8 decimal places.
List controls
Choose how many numbers you need, allow duplicates, and sort the list.
How this random number generator works
This random number generator creates values within your chosen range. Pick integer or decimal output, decide on duplicates, and optionally sort the results before copying.
1. Choose a range
Set a minimum and maximum value for your random number range. Integer mode includes both ends.
2. Pick your options
Choose how many random numbers to generate, whether duplicates are allowed, and whether to sort results.
3. Generate instantly
Generate a new list and copy your random numbers as a comma-separated list.
Why use this random number generator
It is fast, flexible, and designed for everyday use. You get clear controls, instant output, and a clean list you can copy anywhere.
Simple and quick
Generate a list in one click without signup or extra steps.
Flexible options
Switch between integers and decimals, control duplicates, and sort results.
Everyday use
Perfect for games, learning, sampling, and quick data checks.
Common uses for random numbers
Use this random number generator for everyday, non-security tasks where a quick, flexible list of random numbers is useful.
Games and activities
Pick random numbers for games, classroom activities, or quick group selections.
Learning and practice
Create random practice problems, drills, or sample data for math exercises.
Testing and sampling
Generate quick test values or a random subset for reviews and checklists.
Random number generator FAQ
What is a random number generator?
A random number generator produces values that appear unpredictable within a specified range. This tool lets you generate lists quickly with simple controls.
Does the generator include the minimum and maximum values?
Yes. Integer mode includes both ends of the range. Decimal mode can return values at the ends based on the selected decimal places.
How do decimal places affect the results?
Decimal mode generates values at your chosen precision (0 to 8 places). More places create a finer set of possible values within the range.
What is the difference between duplicates and unique numbers?
Duplicates allow the same value to appear more than once. Unique mode ensures each value appears at most once.
How many random numbers can I generate at once?
You can generate up to 100 numbers per batch to keep results fast and readable.
Why can I not request more unique numbers than the range?
Unique results cannot exceed the number of possible values in the range at the chosen decimal precision.
What format are the results in?
Results are shown as a list and can be copied as a comma-separated list for spreadsheets or notes.
Can I use this for lotteries or security?
No. This tool uses standard browser randomness and is not designed for cryptographic security or regulated draws.
Is this random number generator secure?
This tool uses standard browser randomness. It is great for everyday use, but not for cryptographic security or sensitive data.
