U+2AB9 "⪹" Precedes Above Not Almost Equal To Unicode Character
Unicode Version 17.0
⪹
U+2AB9 "⪹" Precedes Above Not Almost Equal To is a mathematical symbol used in formal logic and set theory to indicate that one element precedes another in a defined ordering but does not have an almost equality relation with it, meaning the two values are not approximately or nearly equivalent. This character combines two relations: the concept of precedence or ordering from above, and the explicit negation of an almost equal or approximate equality condition. It is part of the Supplemental Mathematical Operators block and is primarily utilized in advanced mathematical notation to express nuanced relational distinctions that cannot be captured by simpler symbols like "≺" or "≈".
