Detailed Feature Explanations
Minimum Value
Set the lowest number in your random number range. This defines the starting point for number generation:
- Positive numbers: Use for ranges like 1-100, 10-1000
- Negative numbers: Use for ranges like -100 to 100, -50 to 0
- Zero: Start from 0 for ranges like 0-99, 0-1000
- Decimal support: Enter whole numbers only (integers)
Maximum Value
Set the highest number in your random number range. This defines the upper limit for number generation:
- Range validation: Must be greater than minimum value
- Large ranges: Support for ranges up to ±999,999
- Equal values: If min equals max, only that number will be generated
- Practical limits: Consider performance for very large ranges
Quantity
Specify how many random numbers you want to generate in a single operation:
- 1-1000 numbers: Generate from 1 to 1000 random numbers at once
- Single number: Use quantity of 1 for individual random numbers
- Multiple sets: Generate batches for lotteries, games, or sampling
- Performance: Larger quantities may take slightly longer to process
Separator
Choose how to format the output when generating multiple numbers:
