0x87

0x87 is a hexadecimal literal commonly used in programming and data notation. The prefix 0x signals that the digits that follow are in base 16 rather than decimal. In hexadecimal, 0x87 represents the decimal value 135 (8 × 16 + 7).

Because 0x87 denotes a byte or word value, its interpretation depends on context. It often appears in debugging outputs, memory dumps, or source code to express specific bit patterns, flags, or constants. Writers and compilers treat 0x87 as a numeric value unless the surrounding code casts or interprets it as a character.

Character encoding considerations vary with 0x87. In Windows-1252, the byte value 0x87 maps to the double dagger character (U+2021). In ASCII and ISO/IEC 8859-1 (Latin-1), 0x87 is not a printable character and may be treated as a control code or undefined, depending on the environment. Therefore, the visible symbol associated with 0x87 is encoding-dependent rather than universal.

In practice, 0x87 is encountered across languages such as C, C++, Java, JavaScript, and Python wherever hex literals are used. It also appears in contexts like low-level data analysis, firmware updates, and hexadecimal formatting.
