0x9D

0x9D is a hexadecimal literal used in computing to denote a single byte value. It represents the decimal number 157.

In binary, 0x9D corresponds to 10011101. As a one-byte quantity, it occupies eight bits in memory and is commonly encountered in data streams, file formats, and low-level programming.

In practical use, 0x9D may appear as a field value in data protocols, as a component of a color channel, or as part of checksums and other binary encodings. It is often employed in examples that illustrate hexadecimal notation, bitwise operations, and concepts such as endianness and byte alignment.

In character encoding terms, 0x9D is not a printable ASCII character. In Unicode, the code point U+009D lies within the C1 control code range and is generally not associated with a visible symbol in standard text. Legacy encodings may map 0x9D to specific control functions, but it is not intended to represent a standard printable character.

Overall, 0x9D serves as a concrete example of hexadecimal notation used to express an 8-bit value, illustrating how two hex digits delimit a single byte in many programming and data-processing contexts. See also hexadecimal notation, byte (computing).
