Frequently Asked Questions

What can this random number generator be used for?

Our Random Number Generator has numerous applications, including:

  • Creating lottery number combinations
  • Statistical sampling and data analysis
  • Generating PIN codes and passwords
  • Simulation and modeling
  • Game development (dice rolls, card draws, etc.)
  • Educational activities requiring randomization

How random are the generated numbers?

We use JavaScript's Math.random() function enhanced with cryptographic methods to ensure high-quality randomness. Each number is generated independently, providing true random distribution throughout your specified range.

What are the minimum and maximum values I can use?

The generator supports integer values between JavaScript's MIN_SAFE_INTEGER (-9,007,199,254,740,991) and MAX_SAFE_INTEGER (9,007,199,254,740,991), though for practical purposes, we recommend using smaller ranges for better performance, especially when generating large quantities of unique numbers.
