0x7D

0x7D is a hexadecimal literal used in many programming languages to represent the numeric value 125 in decimal. The prefix 0x indicates base-16 notation. In binary, 0x7D is 01111101, which fits within a single 8-bit byte.

In ASCII and Unicode, the code point for the closing curly brace } is decimal 125, which corresponds to hex 0x7D (Unicode code point U+007D). This means the byte value 0x7D represents the character } in ASCII-encoded text.

In practical computing contexts, 0x7D appears as an unsigned 8-bit value ranging from 0 to 255. If treated as a signed 8-bit value (two's complement), 0x7D still represents 125, which is within the positive range (-128 to 127). Hex literals like 0x7D are common in source code for defining constants, bit masks, color components, and data in low-level or performance-sensitive code. For example, a language such as C, C++, Java, or JavaScript allows expressions like 0x7D or 0x7D00 as part of numeric or bitwise operations.

Overall, 0x7D is a compact hex representation of the decimal value 125, with straightforward implications in binary encoding and character sets, and broad applicability in software development as a literal value.
