Online Random Number Generator

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.
