0x1A5A

0x1A5A is a hexadecimal numeric literal widely used in computer programming to represent an integer value. The prefix 0x indicates hexadecimal notation. The value equals 6746 in decimal and fits within 16 bits.

In code, 0x1A5A may appear as a constant in various languages (C, C++, Java, JavaScript, Python). It may be used as a mask, flag, loop counter, or data value; hex literals are convenient for bit-level manipulation and for matching binary patterns.

Endianness: When 0x1A5A is stored in memory as a 16-bit quantity, the order of its bytes depends on endianness. In big-endian, memory would hold 1A followed by 5A; in little-endian, 5A followed by 1A.

In specialized domains, 0x1A5A may appear as a magic number, a firmware constant, or a placeholder in examples. However, there is no canonical meaning associated with 0x1A5A beyond it being a hexadecimal literal; its interpretation depends on the surrounding software or data format.
