0x4B57

0x4B57 is a hexadecimal numeric literal commonly used in computing. In decimal terms, it equals 19383. Hex literals prefixed with 0x are standard in many programming languages, including C, C++, Java, and JavaScript, and are used to express integers, bit masks, memory addresses, or other data in base-16.

When represented as a Unicode code point, the sequence U+4B57 refers to a character in the CJK Unified Ideographs block. The exact glyph shown depends on the font and rendering system, but the code point serves as an identifier for that character within Unicode.

In practical programming contexts, 0x4B57 may appear in source code, hex dumps, or data formats as a 16-bit value. For example, in C or C++: unsigned int x = 0x4B57; assigns the decimal value 19383 to x. Its binary representation is 0100101101010111. Such hex values are widely used for low-level operations, including bitwise manipulation and compact data encoding, where a precise, human-readable representation of a number is advantageous.

There is no widely recognized concept or standard named specifically “0x4B57” beyond its role as a hex literal and, when interpreted as a Unicode code point, as an identifier for a particular character. It thus serves mainly as an example of hexadecimal notation and character encoding in computing.
