Less-than Above Greater-than Above Double-line Equal Symbol
⪑ is a specialized math symbol showing “less-than above greater-than above double-line equal”.
U+2A91
⪑ (U+2A91) is a niche math character used in mathematical notation. It can be useful in documents where you need a compact, stacked comparison/equality style. Here you’ll find copy-ready options and encoding codes.
Less-than Above Greater-than Above Double-line Equal Symbol Meaning
⪑ is a stacked relational/equality symbol. Its Unicode description is “LESS-THAN ABOVE GREATER-THAN ABOVE DOUBLE-LINE EQUAL”, indicating a top-to-bottom arrangement: a “less-than” relation above a “greater-than” relation above a “double-line equal”. Because it’s specialized, you typically see it in formal typesetting, math markup, or font/typography work where exact symbol selection matters. When used, it signals a composite relationship rather than a single operator, so it’s best to employ it where your notation specifically calls for this exact stacked form (for example, in specialized comparison/equality schemes).
Common uses
- •Typing specialized math statements that require a stacked relational/equality operator
- •Using in math documents or lecture notes where the notation must match a specific Unicode symbol
- •Typography/design mockups for scientific or technical layouts requiring precise operator shapes
- •Preparing content for publishing workflows that rely on Unicode symbol correctness
- •Linguistic or notation datasets where each symbol must be preserved exactly
Examples
⪑ Less-than above greater-than above double-line equal
- ⪑Let ⪑ represent the stacked relation in our definition.
- ⪑In the table, the operator is shown as ⪑ for this case.
- ⪑Use ⪑ in the formula for the combined comparison/equality rule.
- ⪑The diagram labels the composite operator as ⪑.
- ⪑Copy ⪑ into the document to keep the notation consistent.
