Frequently Asked Questions
How random are the generated numbers?
The tool uses cryptographically secure random number generation, providing truly random numbers suitable for most applications including security-sensitive uses.
Can I generate numbers with decimals?
The tool generates integers by default. For decimal numbers, you would need to generate integers and divide, or use a different approach.
What happens if I request more unique numbers than the range allows?
If you request more unique numbers than possible in the range, the tool will generate all possible numbers in that range. For example, requesting 100 unique numbers from 1-10 will return all 10 numbers.
Are the numbers truly random?
Yes, the tool uses cryptographically secure random number generation methods that produce truly random numbers, not pseudo-random sequences.
