0x8A

0x8A is a hexadecimal literal used in programming and digital data. The prefix 0x denotes hexadecimal, and the digits 8 and A represent the value 0x8A, which equals 138 in decimal. In binary, 0x8A is 10001010, and it fits within 8 bits.

In software development, 0x8A is commonly used to express a constant byte, for example as a bit mask (to select or clear specific bits), an opcode or data field in binary protocols, or as part of color channel values in some contexts. The interpretation of 0x8A depends on the surrounding data type and protocol.

Character encoding: In ASCII, values 0x00 through 0x7F are defined; 0x8A falls outside and is not a standard ASCII character. In Windows-1252, 0x8A maps to the character Š (Latin capital letter S with caron). In ISO-8859-1, 0x8A is a control character. In Unicode, a single byte 0x8A is not a complete character; the Unicode code point U+008A would be encoded in UTF-8 as two bytes, C2 8A.

Cautions: In languages with signed 8-bit integers, 0x8A may be interpreted as -118 when stored in a signed byte, depending on the compiler and type. When using 0x8A as a numeric constant, ensure the type width and sign are appropriate to avoid unexpected results.
