0x65

0x65 is a hexadecimal literal commonly used in programming to denote a specific numeric value. In hexadecimal, the digits 0-9 and A-F are used; 0x65 equals 6 times 16 plus 5, which is 101 in decimal. In binary, this value is 01100101.

In ASCII and Unicode, the decimal value 101 corresponds to the lowercase letter 'e'. The Unicode code point for this character is U+0065, and in UTF-8 the character 'e' is encoded with a single byte 0x65. Therefore, when 0x65 is interpreted as an ASCII byte, it represents the character 'e'.

Usage and context: 0x65 appears in source code and data as a hex literal, enabling precise specification of values for low-level operations, bit masking, or protocol handling. For example, in languages like C or JavaScript, a variable assigned 0x65 holds the value 101. In data dumps, network packets, or memory layouts, 0x65 may appear as a byte value or part of a larger value when combined with other bytes.
