U+2A9B "⪛" Double-Line Slanted Equal to or Less-Than Unicode Character

Unicode Version 17.0

U+2A9B "⪛" Double-Line Slanted Equal to or Less-Than is a mathematical symbol used in formal logic and relational algebra to denote a combined relationship where a quantity is both equal to and less than another, often within the context of a slanted double-line notation that distinguishes it from ordinary less-than-or-equal signs. Its design merges a slanted double tilde or equals sign with a less-than symbol, creating a single glyph for precise expression in advanced mathematics or computer science. This character is encoded in the Supplemental Mathematical Operators block, serving specialized notation where standard symbols might be ambiguous, and it is less common in everyday text but valuable for theoretical work involving order relations or partial orders.
