About the Random Number Generator
Random Number Generator uses rejection sampling over cryptographic random 32-bit values to avoid modulo bias. Both endpoints are included, and unique mode checks that the requested count fits the range.
How to use the Random Number Generator
- Set integer minimum and maximum.
- Choose quantity and uniqueness.
- Generate and copy the one-per-line results.
Practical tips
- Unique mode becomes slower when requesting nearly every value from a very large range.
- Random numbers do not automatically make a fair experiment if the sampling method is biased elsewhere.
