Web Crypto is used when available; seed forces a deterministic generator. If uniqueness is impossible for the given range, it gracefully falls back to allowing duplicates.
Random Number Generator – Quick Cheat Sheet
Integers: Uniform in [min, max], inclusive. Uses unbiased rejection sampling with Web Crypto.
Floats: Uniform in [min, max) then rounded to your Decimals setting.
Unique: Best with integers. If range < count, the tool auto-disables uniqueness.
Seed: Same inputs + seed → identical output (Mulberry32). Clear seed for cryptographic randomness.
URL params: The address bar updates as you change values, e.g. ?min=1&max=6&count=10.
