0x00002212

0x00002212 is a hexadecimal numeral that corresponds to 0x2212 when leading zeros are omitted. In many technical contexts, this value is used to reference the Unicode code point U+2212, which is the minus sign. It is distinct from the hyphen-minus character U+002D and from longer dash characters such as en dash (U+2013) and em dash (U+2014).

The Unicode character U+2212 is called the minus sign and is used in mathematical notation to denote subtraction or negative values. Its appearance can vary by font, but it is distinct from a simple hyphen; good typography often uses the true minus sign for mathematical expressions to maintain proper spacing.

Encoding and representation details: U+2212 is encoded in UTF-8 as the three-byte sequence E2 88 92. In HTML, it can be represented as − or −. In code, a literal 0x00002212 is the hexadecimal value 8722 in decimal, and its interpretation depends on context—whether it is treated as a numeric constant or as a code point in a Unicode-aware system.

Usage considerations: When typesetting formulas, using the minus sign U+2212 helps ensure correct glyph design and spacing. Relying on the hyphen-minus U+002D can lead to typographic inconsistencies in mathematical content. In programming and data processing, 0x00002212 may appear as a numeric literal or as a code point reference in Unicode handling, depending on the surrounding encoding and parsing rules.
