This is browser-based pseudo-random generation for everyday use, not cryptographic security.

How it works

Generate random values quickly

This Random Number Generator creates one or more random numbers inside a range you choose. You can generate whole numbers, decimal numbers, repeated values, or unique values depending on your need.

It is useful for classroom examples, raffles, simple games, practice problems, quick sampling, choosing winners, creating test data, or making unbiased selections. The generator runs in the browser and does not require account signup.

Set your range

Choose the minimum and maximum values that the generator is allowed to use. The output stays inside that range, making it easy to create dice-like rolls, raffle picks, classroom numbers, or test values.

Generate lists

Create a single number or many values at once. Multiple results are helpful when you need sample data, practice numbers, group assignments, random teams, or repeated game turns.

Avoid duplicates

The unique-only option prevents the same whole number from appearing more than once. This is useful for drawings, seat assignments, random order lists, or any situation where repeat picks would be unfair.

Control the output

Results can stay in random order or be sorted from small to large or large to small. Sorting makes the list easier to read, while random order preserves the original generated sequence.

Frequently asked questions

A random number generator is a tool that selects values from a defined range. This calculator uses browser-based pseudo-random generation, which is suitable for everyday tasks such as games, examples, practice data, and random selections.
Yes. Enter the number of results you want in the count field. The calculator can generate a short list or hundreds of values, depending on your settings. For large lists, sorting the output can make the result easier to review.
Unique-only mode means the same number cannot appear twice in the result. For whole numbers, your range must contain enough available values. For example, you cannot generate 20 unique whole numbers between 1 and 10.
Yes. Increase the decimal places value to generate decimals. For example, 2 decimal places can produce values such as 14.27 or 88.03. Set decimal places to 0 when you only want whole numbers.
You can use it for simple personal or classroom raffles, but you should clearly define the range and unique setting before drawing. For official contests, follow your local rules and use any required audit or transparency process.
No. This generator is intended for everyday random picks and learning use. It is not a cryptographic random generator and should not be used for passwords, encryption keys, security tokens, or sensitive authentication codes.
