How the Générateur et Roulette de Nombres Aléatoires Settles random values and utility picks
The Générateur et Roulette de Nombres Aléatoires exists for one specific failure mode: needing an unbiased value fast without opening a spreadsheet. It loads with 10 ready-made entries (1, 2, 3, 4, and more) so you can spin within a couple of seconds, then swap in your own list when the defaults do not match your situation.
What you get out of it is a reproducible, shareable generator instead of an ad-hoc guess. The stopping angle comes from window.crypto.getRandomValues() rather than Math.random(), and each slice occupies an arc exactly proportional to its weight — so the visual you see on the canvas is a literal picture of the odds. Génération de numéros uniques and idéal pour remplacer les dés ou bulletins physiques are both available while the wheel is live.
Typical use looks like this: Tirage de numéros de loterie et tombola. Developers, testers, teachers, hobbyists tend to reach for it most, usually because the alternative — spreadsheet rand() formulas or math.random snippets — either takes longer or invites argument. Recommended setup: Quick 2.5-second spin; weighting off unless you need skewed odds.
