U+2A75 "⩵" Two Consecutive Equals Signs Unicode Character
Unicode Version 17.0
⩵
U+2A75 "⩵" Two Consecutive Equals Signs is a mathematical typographic symbol that represents a double equals sign used primarily in logic and computer science to denote a logical equivalence relation or, in some programming contexts, a strict equality comparison distinct from a single equals sign assignment. It is part of the Supplemental Mathematical Operators block, which includes various symbols intended for advanced mathematical notation. While visually similar to the standard double equals sign (==) commonly seen in code, the Unicode glyph is a single, unified character positioned as a continuous horizontal pair, ensuring unambiguous rendering across different fonts and platforms for formal documents.
