0x2A0

0x2A0 is a hexadecimal integer literal used in many programming languages. The prefix 0x signals base-16 notation, and the digits 2, A, and 0 correspond to the hexadecimal value 2A0. In decimal, this value is 672. Hex literals like 0x2A0 are commonly used to denote numeric constants, memory addresses, bit masks, or offsets in software and hardware contexts.

In Unicode, the code point U+02A0 identifies a specific character: the modifier letter glottal stop. This character is part of the IPA Extensions block and is used in phonetic transcription. The numeric value 0x2A0 and the code point U+02A0 share the same underlying hexadecimal representation, though the Unicode naming convention is U+02A0 rather than 0x2A0.

Applications vary: in text rendering, fonts map U+02A0 to a glyph whose appearance depends on the font; in linguistic notation, it marks a glottal stop that is modified by a preceding or following element. In computing, a literal like 0x2A0 often appears in source code or configuration files to set addresses, masks, or initialization values.

Because 0x2A0 falls outside the ASCII range, it may not be representable as a single byte in older encodings and often requires at least two bytes in UTF-8 when representing the corresponding Unicode code point.
