FAQ
Are these truly random?
We use JavaScript Math.random(), a pseudo-random number generator (PRNG). Sufficient for general use. For cryptographic needs, use a dedicated crypto tool.
What are the limits of unique mode?
Unique mode is limited by range size and precision. For example, range 1-10 with 0 decimals yields at most 10 unique numbers. The system auto-adjusts if count exceeds this.
How many numbers can be generated at once?
Up to 10,000 random numbers per generation.
