Random Number Generator — quick guide
1) Core idea
Generate random integers, decimals, list picks, and passwords with uniform selection and simple controls.
2) How this tool works
- Integers: uniform over [min, max], inclusive.
- Decimals: uniform over [min, max] then rounded to N places for display.
- List: random selection without bias; password: random chars from chosen pool.
3) Sanity checks
- min ≤ max; quantity ≥ 1.
- Decimal places between 1 and 10.
- Password length within 4–128.
4) Shortcuts that help
- Use presets like Dice (1–6) or Coin Flip (0–1).
- Increase quantity for bulk outputs; clear history when done.
- Stick to integers for lottery-style draws.
5) Common pitfalls
- Setting min > max.
- Using too few decimal places for precise simulations.
- Picking more list items than available unique entries.
6) Micro-examples
- Integers 1–6, count 3 → e.g., 2, 6, 4.
- Decimals 0–1, 3 places → e.g., 0.137.
- List [A,B,C], pick 2 → e.g., B, A.
7) Mini-FAQ
- Distribution? Uniform for integers/decimals in this tool.
- Crypto secure? Uses standard Math.random(); not cryptographically secure.
- Bias? Ranges are inclusive; list picks avoid favoring specific positions.
8) Action tip
Set sane bounds, then generate a batch and review the history for quick selections or repeats.
