U+22CD "⋍" Reversed Tilde Equals Unicode Character
Unicode Version 17.0
⋍
U+22CD "⋍" Reversed Tilde Equals is a mathematical symbol combining a reversed tilde above an equals sign, primarily used in formal logic and mathematics to denote a specific relational or equivalence concept distinct from standard equality or approximation. It often represents a relation that is both symmetric and transitive in certain contexts, such as in set theory or abstract algebra, where it may signify an alternative form of equivalence or a reversed logical connection. While less common than its standard counterpart, the tilde operator or congruence symbols, this glyph serves as a precise notation in specialized academic texts and technical documentation to clarify nuanced relationships between mathematical expressions.
