U+2AAF "⪯" Precedes Above Single-Line Equals Sign Unicode Character
Unicode Version 17.0
⪯
U+2AAF "⪯" Precedes Above Single-Line Equals Sign is a mathematical symbol that represents a relation where one element precedes another, possibly with an equivalence implied by the single-line equals sign beneath it. It is often used in formal logic, order theory, or lattice theory to denote a precedence relation that is combined with or modified by equality. The symbol visually combines a curved or angled "precedes" shape with a straight horizontal equals sign directly below it, distinguishing it from similar characters like the double-line "precedes or equal to" symbol. Its encoding in Unicode allows for precise representation in digital text, ensuring clarity in mathematical notation across different systems and fonts.
