0x1a58

0x1A58 is a hexadecimal numeric literal, where the 0x prefix indicates base-16 notation. In decimal form, the value is 6744. The digits 1, A, 5, and 8 are valid hex digits (0–9 and A–F), and the same value can be written with different letter cases, for example 0x1a58 or 0x1A58.

In programming, such literals are used to express numbers succinctly and are common across languages influenced by the C syntax, including C, C++, Java, JavaScript, Python, and many others. They are interpreted as unsigned or signed integers depending on the language and context, and their exact type may be determined by how they are used (for example within an assignment or as a bitfield).

Hex literals like 0x1A58 also appear in low-level contexts, such as memory addressing, bitwise operations, and hardware interfacing. The value fits within 16 bits (0x0000 to 0xFFFF); when stored in memory, the physical byte order depends on the system’s endianness, even though the numeric value remains 6744.

In data representation, hex values are frequently used to illustrate color codes, register values, or masks. When used to describe colors in 16-bit color systems (such as RGB565), 0x1A58 encodes a specific combination of red, green, and blue components according to the relevant bit layout.

Overall, 0x1A58 serves as a concise example of a small hexadecimal constant commonly encountered in software development and digital electronics.
