Random Number Generator
Generate random numbers within a custom range.
Specify minimum, maximum, and how many numbers to generate.
Generated Numbers
This tool generates pseudo-random integers within your specified range (inclusive of both minimum and maximum values).
Formula:
Random Integer = Math.floor(Math.random() × (max - min + 1)) + min
How it works:
Math.random()produces a decimal between 0 (inclusive) and 1 (exclusive)- The result is scaled to your range and rounded down to a whole number
- Each number is generated independently
Common uses:
- Dice rolls: Min 1, Max 6
- Coin flip: Min 0, Max 1 (0 = tails, 1 = heads)
- Lottery numbers: Set your range and quantity
- Random selection: Pick winners, assign groups, or randomize order
- Games and simulations: Generate random scenarios
Note: This uses JavaScript’s built-in pseudo-random number generator, which is suitable for games and general use but not for cryptographic purposes.
