What is a Random Number Generator?
Random Number Generator is a tool for producing pseudorandom numbers in a specified range for simulations, testing, examples, games, or everyday decision-making. It can generate integers and floating-point numbers with customizable precision.
The generator uses the 'random' JavaScript library. It is useful for non-security work such as mock data, classroom examples, and casual sampling, but it should not be used for passwords, tokens, regulated drawings, or security decisions.
Key Benefits:
- Flexible Range: Set any minimum and maximum values from negative to positive numbers
- Batch Generation: Generate up to 100 numbers at once with one click
- Duplicate Control: Choose to allow or prevent duplicate numbers in results
- Number Types: Generate integers or floating-point numbers with custom decimal precision
- Visual Layout: Customizable column display (1-10 columns) for better readability
Useful for developers, educators, and anyone who needs configurable random-looking numbers for testing, analysis practice, or informal decisions.
