0x000A

0x000A is the hexadecimal notation for the value 10, widely used in computing to denote the line feed control character in ASCII and Unicode. In Unicode, U+000A is the LINE FEED (LF) character, a non-printing control code used to indicate a line break rather than a visible symbol.

In ASCII and Unicode text, 0x0A commonly represents a newline. In many programming languages, the newline character is represented as \n, which encodes the value 0x0A. In Unicode escapes this is written as \u000A. In UTF-16 encoding, U+000A can be stored as 000A in big-endian or 0A00 in little-endian.

End-of-line conventions differ by platform. Unix-like systems typically use LF (0x0A) alone to mark the end of a line, while Windows uses a two-byte sequence of CRLF (0x0D 0x0A). In contrast, classical Mac OS used 0x0D as the line terminator. The 0x0A value is the second byte of the Windows CRLF sequence and is the standalone line terminator in Unix-style text files.

In practical terms, 0x000A affects how text is displayed, printed, and processed. It appears in hex dumps, string literals, and data streams whenever a line break is needed. It is a fundamental part of text encoding schemes and is ubiquitous in data interchange, file formats, and programming.
