The ⋍ (Reversed Tilde Equals) symbol features a standard equals sign topped with a horizontally flipped tilde. In mathematics, it acts as a relational operator to denote specific types of equivalence, isomorphism, or approximation, visually distinguishing it from the standard asymptotically equal sign (≃). While rarely used in everyday text, it remains an essential typographic tool in advanced algebra and technical documentation.
