Random Number Generator
Generate one or more random numbers within a specified range, with options for integers or decimals.
The Random Number Generator is a versatile tool for producing random numbers within a custom range. It's an essential utility for a wide array of tasks, from statistical sampling and simulations to gaming and contests. All numbers are generated using your browser's built-in cryptographic pseudo-random number generator, ensuring a high degree of randomness for most applications without compromising your privacy by sending data to a server.
- Gaming: Picking a random number for a lottery, raffle, or any game of chance.
- Testing & Development: Generating random values for test data or simulations.
- Education: Teaching concepts of probability and statistics.
- Decision Making: A simple way to make an unbiased choice between several options (e.g., 'pick a number from 1 to 5').
Are these numbers truly random?
This tool uses `Math.random()`, a pseudo-random number generator (PRNG). For everyday purposes like games or picking winners, it is effectively random. However, it is not suitable for cryptographic applications that require true unpredictability.
Can I generate negative numbers?
Yes. Simply set the 'Minimum Value' to a negative number to include it in the possible range.
Is my data secure?
Yes. All number generation happens on your device in your browser. Nothing is ever sent to our servers.
