0x2D

0x2D is a hexadecimal literal used in computing to denote the byte with hexadecimal value 2D. In decimal, this value is 45.

In ASCII and Unicode, 0x2D corresponds to the hyphen-minus character '-' (Unicode U+002D). This character is commonly used to join words, indicate subtraction, or mark ranges in text.

In programming languages such as C, C++, JavaScript, and Python, 0x2D is a literal that evaluates to 45. It also appears when representing the hyphen character in binary data, encoded text, or protocol messages.

In web and data formats, the hyphen appears in identifiers, filenames, and URLs. When percent-encoding is used for URLs, the hyphen is encoded as %2D, preserving the same hexadecimal value.

In blockchain and data-serialization contexts, the 0x prefix denotes hexadecimal data; a single byte 0x2D is not typically a standalone value like an address, but it can appear as part of larger byte sequences, fingerprints, or checksums.

Summary: 0x2D represents the hexadecimal value 2D, which equals decimal 45 and maps to the hyphen-minus character in ASCII and Unicode. It is a common literal in programming and appears in various encoding schemes as the underlying byte value for the hyphen.
