What Is a Base (Number System)?
A number base defines how many unique digits are used before “carrying over.” For example, decimal (base-10) uses digits 0–9, while binary (base-2) uses only 0 and 1.
| Base | Name | Digits | Example |
|---|---|---|---|
| 2 | Binary | 0–1 | 1011₂ = 11₁₀ |
| 8 | Octal | 0–7 | 17₈ = 15₁₀ |
| 10 | Decimal | 0–9 | 255₁₀ |
| 16 | Hexadecimal | 0–9, A–F | FF₁₆ = 255₁₀ |
| 36 | Max | 0–9, A–Z | AZ₃₆ |
