0x9B

0x9B is a hexadecimal numeric literal used in computing to denote the value 155 in decimal. The prefix 0x is a conventional notation adopted by the C programming language and many others to indicate that the number following it is in base 16.

In data representation and programming, 0x9B appears as a single byte value within the 0x00–0xFF range. It can show up in source code, binary data, memory dumps, network packets, and debugging tools. When used as a color channel in hexadecimal form, 0x9B represents a channel value of 155, which corresponds to a mid-to-high intensity on that channel if shown as part of an RGB color component.

In Unicode and text encoding, the code point U+009B corresponds to a C1 control character and is not a printable symbol. As such, 0x9B is typically treated as a non-printing control in contexts that rely on the full range of Unicode’s C1 controls.

Overall, 0x9B serves as a representative example of hexadecimal notation in computing: a compact way to express a byte-sized value that can occur in programming, data formats, and various low-level contexts.
