0x2e

0x2E is the hexadecimal representation of the decimal number 46. The prefix 0x is commonly used in programming languages to denote a base-16 literal, so 0x2E is read as the value two, ten, summing to 46 in decimal.

In ASCII and Unicode, the value 0x2E corresponds to the period character, the punctuation mark used to end sentences. In Unicode this character is encoded as U+002E. When a program interprets the numeric value 0x2E as a character code, it yields the dot character '.'.

In practical terms, 0x2E often appears in code and data as a hex representation of a dot. For example, in C or C-like languages you might see a statement like printf("%c", 0x2E); which prints a period. Hex dumps and network or file formats sometimes display text by listing the byte values in hexadecimal, with 0x2E representing the same period character.

Beyond its role as a punctuation mark, 0x2E has no independent semantic meaning in computing beyond its character representation; its significance is tied to the character encoding in use (ASCII or Unicode) and to the common programming convention of writing numeric literals in hexadecimal form.
