Random Number Generator

Need a random number? This generator creates random numbers within any range you specify. Whether you need a single random pick for a game, multiple numbers for a lottery simulation, or random decimal values for testing, simply set your minimum, maximum, and count to generate instantly.

This random number generator uses JavaScript's Math.random() function to produce pseudorandom numbers uniformly distributed across your specified range.

Features:

  • Set any minimum and maximum value (the generator handles reversed ranges automatically)
  • Generate up to 20 numbers at once
  • Toggle between whole numbers (integers) and decimals
  • See the sum and average of generated numbers

Common uses:

  • Picking random winners or drawing names
  • Dice rolling and board game number generation
  • Generating test data for software development
  • Statistics exercises and simulations
  • Random sampling for surveys or experiments

Note: This generator uses pseudorandom numbers, which are suitable for games, simulations, and everyday use. For cryptographic applications or high-security contexts, a cryptographically secure random number generator (CSPRNG) should be used instead.
