How the Random Number Generator Works
This tool generates random numbers within your specified range using a cryptographically strong algorithm:
Basic Features:
Range: Set minimum and maximum values for your numbers
Quantity: Choose how many numbers to generate
Decimals: Control decimal precision of the results
Advanced Features:
Sorting: Automatically sort numbers in ascending order
Unique values: Generate only unique numbers (no duplicates)
Formatting: Customize prefixes, suffixes, and separators
Seed value: Create reproducible random sequences
Exclusion range: Skip numbers within a specific range
History: Save and recall previous generations
Use Cases:
Creating random test data for software development
Generating lottery numbers or game values
Statistical sampling and simulations
Random selection processes
Educational purposes for probability demonstrations
Technical Details:
The generator uses the Web Cryptography API when available for cryptographically strong random values, falling back to a high-quality pseudo-random algorithm when needed. For integer generation, it uses uniform distribution across the specified range.
