Number Systems in Computer Science: A Complete Developer Reference Computer science uses multiple number systems, each suited to a specific context. Binary for hardware-level operations, octal for file permissions, decimal for human-facing output, hexadecimal for memory addresses and color values, BCD for financial calculations that can't afford rounding, Gray code for analog-to-digital converters. This is the reference you keep open when you need to quickly cross-check a value, remember a formula, or understand why a particular system is used in a specific domain. ------|---------| | Decimal → binary | Repeated division by 2, remainders bottom-to-top | | Binary → decimal | Sum of | | n-bit unsigned range | 0 to | | n-bit signed (two's complement) | to | | Negative in two's complement |…
