0x12B3

0x12B3 is a hexadecimal numeral written with the 0x prefix, commonly used in computing to denote a base-16 integer. Interpreted in base-10, 0x12B3 equals 4787. The digits used are 0–9 and A–F (case-insensitive). In programming, such literals are a convenient way to express values that are naturally aligned with binary or hardware representations.

In languages with C-style literals, 0x12B3 represents an unsigned integer value. It can be assigned to a variable, used in bitwise operations, or serve as an address offset. For example, a programmer might write int a = 0x12B3; or unsigned short w = 0x12B3; Its meaning depends on the surrounding code, the data type, and the architecture.

Common contexts where 0x12B3 may appear include memory addressing in low-level code, offsets within data structures, or as a placeholder example in technical documentation. The exact interpretation is determined by how the value is used and the system in which it appears.

Hex values like 0x12B3 can also appear in data encodings, such as color representations in certain 16-bit formats (for example RGB565) or as portions of broader binary formats. The same literal can thus represent different things in different applications, underscoring the importance of context.

Origin and standardization: 0x12B3 has no inherent meaning beyond its numeric value and syntax. It is a common form for representing numbers in hexadecimal, but it is not a universal identifier on its own.
