Random Number Generator
Generate random integers or decimals in any range with bulk mode.
About This Tool
Generates cryptographically-weak but statistically uniform random numbers using the browser's Math.random(). Choose any min/max range, integer or float output, and optionally ensure all values are unique (integers only).
Use Cases
Lottery picks, random sampling, test data generation, game development, and statistics exercises all benefit from fast bulk random number generation.
FAQ
- Is this cryptographically secure? β No. Math.random() is not suitable for security-critical use. Use the Hash Generator or Password Generator for secure random values.
- Unique mode limit? β Unique mode is limited to integers and will generate at most (max - min + 1) values.
