U+2B40 "⭀" Equals Sign Above Leftwards Arrow is a typographical symbol that combines an equals sign placed directly above a leftward pointing arrow, functioning in specialized notation to indicate logical equivalence or bidirectional implication, particularly in fields like mathematics, logic, and computer science where it may denote that a leftward directional relationship holds with equality, or that the leftward arrow carries the same truth value as the expression it follows, though its usage is rare and largely confined to academic or technical contexts rather than standard punctuation.
