U+229D "⊝" Circled Dash Unicode Character
Unicode Version 17.0
U+229D "⊝" Circled Dash is a mathematical and technical symbol that represents a logical operator for negation or exclusivity, often used in contexts like formal logic, set theory, or algebra to denote a "not" or "minus" relation within a circular enclosure. Its appearance consists of a single horizontal line or dash centered inside a circle, distinguishing it from similar symbols such as the circled plus or minus signs. This glyph belongs to the block of Unicode characters known as Mathematical Operators and serves as a visual shorthand in academic notation, particularly in texts discussing binary operations or lattice theory. While less common than its counterparts, the circled dash provides a clear, concise way to indicate a specific logical or arithmetic function in specialized mathematical writing.
