Random Number Generator

This tool uses the browser's built-in Math.random() function, which produces pseudo-random numbers. It is suitable for games, sampling, simulations and everyday tasks. For cryptographic purposes, a dedicated CSPRNG library should be used instead.

Yes. Uncheck "Allow duplicates" and the tool will ensure every generated number is unique. Note that the count cannot exceed the available range — for example, you cannot generate 50 unique integers between 1 and 10.

You can generate up to 1,000 numbers at a time. This limit keeps the tool responsive in the browser while covering most practical use cases.

Yes. Uncheck "Integers only" and the tool will produce decimal numbers within your range. The results are shown with up to 6 decimal places.

When "Sort results" is enabled, the generated numbers are arranged in ascending order (smallest to largest) before being displayed. This is useful when you need an ordered dataset.
