U+2256 "≖" Ring in Equal To Unicode Character
Unicode Version 17.0
≖
U+2256 "≖" Ring in Equal To is a mathematical symbol that modifies the standard equals sign by placing a small ring or circle directly above the horizontal bars, indicating a specific relational operation or constraint. It is most commonly used in mathematics to denote equality with an additional condition, such as approximate equality or a geometric congruence, depending on the context. This character is part of the Unicode Mathematical Operators block and is encoded for use in digital text to represent relationships that are not served by the plain equals sign. Its appearance helps distinguish specialized equalities in technical documents, formulas, and academic writing.
