What is Random Number Generation?
Random number generation is the process of creating sequences of numbers that lack any pattern and cannot be predicted. These numbers are essential for simulations, games, statistical sampling, cryptography, and testing applications where unpredictability is required.
Integer Range
1 to 100 → 47
Decimal Precision
0.0 to 1.0 → 0.847
Unique Sets
5 unique → 3,7,1,9,5
Lists
10 numbers → [...]

Frequently Asked Questions
How random are the generated numbers?
The generator uses cryptographically secure pseudo-random algorithms that produce statistically random numbers suitable for most applications, including security-sensitive uses.
Can I generate truly unique numbers?
Yes! Enable the "Unique Numbers" option to ensure no duplicates in your generated set. The maximum count will be limited by your range size.
What's the difference between decimals and precision?
Decimals allow fractional numbers (like 3.14), while precision controls how many decimal places to include (e.g., 2 places gives 3.14, 4 places gives 3.1416).
Can I generate negative numbers?
Absolutely! Set a negative minimum value to include negative numbers in your range. For example, -100 to 100 will generate both positive and negative numbers.
