How is this different from a dice roller?

The dice roller uses Math.random() and is designed for entertainment. The random number generator uses crypto.getRandomValues, which is cryptographically secure — safe for giveaways and draws.

Does it avoid modulo bias?

Yes. The implementation uses rejection sampling: it generates uint32 values and discards any that fall outside the largest clean multiple of the range, so every number in the range has exactly equal probability.

Can I generate negative numbers?

Yes. Any integer minimum and maximum are supported, including negative values.
