What is this?
A random number generator produces numbers within a specified range. Integer mode gives whole numbers; decimal mode gives numbers with decimal places. Uses pseudo-random generation. Set minimum and maximum, choose integer or decimal, and generate. Each click produces a new random value. Generate one at a time or multiple at once. The random numbers are suitable for games, sampling, and testing—not for cryptography or security. For security-sensitive applications, use a cryptographically secure random source. The tool is simple and fast. No signup or configuration needed. Perfect for quick randomization needs.
When to use
Use for games (dice, lotteries), sampling, testing, or simulations. Example: Random 1–6 for dice. Random 1–100 for percentage. For cryptography, use a secure random source. Game players roll dice. Teachers pick random students. Developers need test data. Researchers do random sampling. Pick raffle winners. Simulate random events. Essential for fairness and variety. Generate multiple numbers for bingo or sampling. Remember: not for passwords or security. Use for fun and practical randomization.
How to use
Set the minimum and maximum values, choose integer or decimal mode, and click "Generate" to create a random number. Use "Generate 10" to create multiple numbers at once.
Tips
- Minimum must be less than maximum.
- Integer mode generates whole numbers only.
- Decimal mode generates numbers with decimal places.
Frequently asked questions
- Set the minimum and maximum values, choose integer or decimal, and click "Generate". The tool uses cryptographically secure random generation when available.
- Integer mode generates whole numbers only (e.g., 1, 5, 100). Decimal mode generates numbers with decimal places (e.g., 1.23, 5.67, 100.45).
- The tool uses Math.random() for generation. For cryptographic security, use a dedicated secure random number generator. For most purposes (games, sampling, etc.), Math.random() is sufficient.
- Yes. Click "Generate" multiple times or use "Generate 10" to create multiple random numbers. Each generation is independent.
