Random Number Generator
Use this random number generator to create one or more random numbers inside a custom range, with optional decimals or unique-value mode.

- Create decimal samples for testing or mock data.
- Pick unique numbers from a finite range without repeats.
Random Number Generator Explained
A random number generator creates unpredictable numeric values inside a range you choose. This version can produce integers or decimals, generate multiple outputs at once, and optionally avoid duplicates when you need unique integers. It is useful for testing, lightweight simulations, games, sample data, and everyday picks like drawing a number from a range. Because it runs instantly in the browser, you can change the bounds and get new output without any backend or page reload. That makes it a simple but very flexible utility.
FAQ
Can it generate decimals?
Yes. Set the decimal precision above zero to generate decimal values instead of integers only.
What does unique mode do?
It prevents duplicates, but only works when the integer range is large enough for the requested count.
Is this useful for testing?
Yes. It is handy for quick sample data, range testing, and light simulation work.
