0x1E3

0x1E3 is a hexadecimal numeric literal commonly used in computing to denote the decimal value 483. In programming languages that adopt the 0x prefix, such as C, C++, Java, and JavaScript, 0x1E3 represents the same numeric value as 483 in base-10.

As a value, 0x1E3 equals 483 in decimal. Its binary representation is 111100011. The hex form is compact and convenient for reading memory layouts, bit masks, and low-level operations, where each hex digit corresponds to four binary bits. Because the meaning of 0x1E3 depends on the surrounding code, it can represent an integer constant, an address offset, a color component in some shader code, or other domain-specific numeric data.

In addition to general programming usage, hex values often appear in discussions of character encoding and Unicode. The Unicode code point U+01E3, which also encodes the hexadecimal value 01E3 (equal to 483 decimal), corresponds to the Latin small letter a with macron (ǣ). Although U+01E3 and 0x1E3 share the same underlying value, they inhabit different contexts: one is a Unicode code point, the other a programming literal.

Overall, 0x1E3 serves as a practical example of how hexadecimal notation functions in software development and how numeric values can cross-domain boundaries between code literals and standardized character encodings. See also hex numeral systems, memory addressing, and Unicode code points.
