0xAF

0xAF is a hexadecimal numeral commonly used in computing to denote the byte value 175 in decimal. The prefix 0x indicates hex notation in many programming languages such as C, C++, Java, and JavaScript.

In binary, 0xAF equals 10101111. As a single byte, it's within the range 0x00 to 0xFF. If interpreted as an unsigned 8-bit integer, its value is 175. If interpreted as a signed 8-bit integer using two's complement, its value is -81.

Character encoding: The byte value 0xAF corresponds to the Unicode code point U+00AF, the macron symbol ¯, in ISO-8859-1 (Latin-1) and Windows-1252 encodings. In Unicode, it is distinct from the ASCII range and requires an extended character set for display.

Common uses: 0xAF appears in source code as a literal byte, in low-level programming, embedded systems, and networking when representing raw data, bit patterns, or color channels. For example, a color channel value of 0xAF would be 175 on a 0–255 scale. It may also serve as part of memory addresses, masks, or protocol fields where a specific byte value is meaningful.

Notes: Like other hex literals, 0xAF is a concise way to express a fixed 8-bit value and is widely supported across programming languages and data formats. Its interpretation depends on the context, including whether the value is treated as signed or unsigned and which encoding scheme is in use.
