How it works

The tool generates a random number uniformly between your minimum and maximum values, then formats it using the selected number of decimal places.

Examples

  • 0% to 100% → common full-range percentage
  • 25% to 75% → mid-range random percentage
  • 90% to 100% → high-probability style range
