0x4D21

0x4D21 is a hexadecimal numeral commonly used in computing and digital systems. As a hex value, it represents the decimal number 19745 (4 × 4096 + 13 × 256 + 2 × 16 + 1). Hex literals are frequently employed to express memory addresses, bitmasks, color values, or constant data in source code.

In the Unicode standard, the code point U+4D21 lies within the CJK Unified Ideographs block. This means the value corresponds to a single character used in East Asian writing systems. The exact glyph and its meaning depend on the font and language context; the code point identifies the character independent of its visual representation.

From a data-encoding perspective, 0x4D21 can be viewed as two bytes: 0x4D and 0x21. In big-endian order, the byte sequence is 4D 21; in little-endian order, it becomes 21 4D. If interpreted as ASCII (when applicable), 0x4D corresponds to the letter 'M' and 0x21 corresponds to '!'. However, in Unicode or binary data contexts, these bytes may serve as part of a larger value rather than as text.

Common uses of 0x4D21 include serving as a numeric constant in software, encoding binary data, or denoting a specific code point in Unicode-related processing. Its role is determined by the surrounding system, endianness, and interpretation scheme.
