U+227C "≼" Precedes or Equal To Unicode Character
Unicode Version 17.0
≼
U+227C "≼" Precedes or Equal To is a mathematical symbol used in order theory and set theory to indicate that one element comes before or is equivalent to another in a partial order. It combines the concepts of precedence and equality into a single relational operator, often employed in contexts involving posets (partially ordered sets) or in formal logic to express a non-strict ordering relationship. This character helps clarify comparisons where an element is either less than or exactly equal to another, avoiding the ambiguity of separate symbols. It is distinct from the similar "less-than-or-equal-to" sign (≤) and is primarily used in specialized mathematical notation.
