0x1572

0x1572 is a hexadecimal numeric literal commonly used in computing and programming. The prefix 0x indicates that the digits following it are in base 16, rather than decimal. As a value, 0x1572 represents the decimal number 5490.

In different representations, 0x1572 can be expressed as:

- Decimal: 5490

- Binary: 0001 0101 0111 0010

- Octal: 12562_8

- Hexadecimal: 0x1572 (itself)

To understand its arithmetic properties, 5490 is an even number with the prime factorization 2 × 3^2 × 5 × 61.

In practical computing contexts, 0x1572 may appear as a constant in source code, used for bitwise operations, memory addressing, or as a numeric parameter in functions. Many programming languages—such as C, C++, Java, JavaScript, and Python—recognize the 0x prefix as denoting hexadecimal literals, which are often chosen for readability when dealing with bit patterns, hardware registers, or color values in some formats. When stored in memory as a 16-bit unsigned value, the representation is 0x1572; in little-endian systems, this value would be stored as the bytes 0x72 followed by 0x15, whereas in big-endian systems it would be stored as 0x15 then 0x72.

It should not be confused with Unicode code points written in the U+ notation (for example, U+1572), which denotes a different kind of identifier.
