Double-line Equal To Or Less-than Symbol
⪙ denotes a “double-line equal to or less-than” comparison in mathematical notation.
U+2A99
⪙ is a specialized mathematical comparison symbol: double-line equal to or less-than. It’s mainly used in contexts that require precise typographic notation. Use it when standard ≤ or =/≤ symbols aren’t sufficient for your formatting needs.
Double-line Equal To Or Less-than Symbol Meaning
⪙ (Unicode U+2A99) is named “double-line equal to or less-than.” In mathematics, it expresses a comparison between values, indicating “equal to or less than,” presented with a double horizontal stroke to distinguish it from related operators (such as ≤). Because it’s a distinct Unicode character, it’s often used in documents, textbooks, and technical writing where a specific typographic variant is needed. When you copy it into text, make sure the font you’re using supports U+2A99; otherwise, it may render as a placeholder box.
Common uses
- •Writing technical mathematics or lecture notes with a specific comparison notation.
- •Labeling conditions in academic documents where a distinct “≤” variant is required.
- •Preparing equations in publishing tools or document editors that support Unicode math symbols.
- •Designing math-themed graphics, posters, or infographics that need exact operator styling.
- •Creating content for tutorials and references that must match a textbook’s symbol set.
Examples
⪙ Double-line equal to or less-than
- ⪙If x ⪙ y, then x is allowed to be equal to y or smaller than y.
- ⪙The set {x | x ⪙ 3} contains all real numbers up to 3, including 3.
- ⪙We define feasibility as: condition ⪙ holds for the chosen parameters.
- ⪙In the inequality system, replace the operator with ⪙ to match the notation standard.
- ⪙The constraint can be written using ⪙ to indicate “equal or less than.”
