Numeral System Reference
| Format | Symbols Used | What It Means | Engineering Example |
|---|---|---|---|
| Binary (Base 2) | 0-1 | Bit-level representation | Feature flags and bitmasks |
| Octal (Base 8) | 0-7 | Compact grouping of binary bits | POSIX file permissions like 755 |
| Decimal (Base 10) | 0-9 | Human-default counting system | User-facing IDs and metrics |
| Hexadecimal (Base 16) | 0-9, A-F | Compact byte-oriented representation | Hashes, memory dumps, color values |
FAQ
Why does hexadecimal matter so much in debugging?
Hex maps cleanly to bytes (two hex digits per byte), making it easier to inspect binary payloads, IDs, and checksums.
What does Auto Detect look for?
Auto mode checks common prefixes and patterns such as 0x for hex, 0b for binary, and plain numeric text for decimal.
