How Random Number Generator works
Use rejection sampling on browser cryptographic random bytes to draw unbiased integers.
Whole-number bounds only, with minimum no greater than maximum. Up to 1,000 draws. Sampling is with replacement, so duplicates are possible.
How to use Random Number Generator
Start with your own input.
Enter minimum integer
Replace the example with the minimum integer you want to process. Whole-number bounds only, with minimum no greater than maximum.
