0x75

0x75 is the hexadecimal numeric literal representing the value 0x75 (decimal 117). In hexadecimal notation, the 0x prefix indicates base-16 numbers, with digits 0–9 and letters a–f used to express values from 0 to 15 in each position.

In computing, 0x75 often denotes a single byte whose value is 0x75. In ASCII, the byte 0x75 encodes the lowercase letter 'u'. The Unicode code point U+0075 corresponds to the same character, reflecting the alignment between ASCII and the first block of Unicode for basic Latin letters.

In x86 machine code, 0x75 is the opcode for a short conditional jump, commonly represented as JNZ (Jump if Not Zero) or JNE (Jump if Not Equal), with an 8-bit signed displacement. This single-byte opcode enables a compact branch instruction within a small distance, making 0x75 a familiar value in discussions of low-level instruction encoding.

Because 0x75 is a single-byte value, it appears frequently in byte-oriented data, memory dumps, and examples illustrating hex notation, byte manipulation, and low-level programming concepts. In high-level languages, 0x75 is treated as the integer value 117 unless used to initialize a byte or character type, where it represents the corresponding 8-bit value.

Overall, 0x75 is notable for its dual role as a hex representation of the numeric value 117 and as a concrete opcode in the x86 instruction set, as well as its interpretation as the ASCII/Unicode character 'u' in text data.
