Neither Greater-than Nor Less-than Symbol
≹ denotes “neither greater than nor less than.”
U+2279
The symbol ≹ is the mathematical relation “neither greater-than nor less-than.” It’s used when a statement excludes both strict greater-than and strict less-than. This makes it handy for comparisons and logic where only equality or indeterminate cases matter.
Neither Greater-than Nor Less-than Symbol Meaning
≹ (NEITHER GREATER-THAN NOR LESS-THAN) is a relational symbol used to indicate that one value is not strictly greater than another and also not strictly less than another. In many mathematical and logical contexts, this can be read as “not greater and not less,” leaving equality as the typical remaining possibility (though exact interpretation depends on the system’s rules, especially when dealing with partial orders or special values). It’s often used to exclude ordering relationships in proofs, definitions, and constraint statements, and it can help communicate “no strict comparison direction” more compactly than plain text.
Common uses
- •Defining constraints in math and logic expressions where neither strict ordering direction is allowed
- •Documenting comparison rules in specifications or formal notes
- •Writing inequalities in educational materials that exclude both greater-than and less-than
- •Representing “not comparable in either direction” in discussions of ordering or partial comparisons
- •Styling math-heavy UI text (labels, tooltips, or diagrams) to show “neither > nor <” succinctly
Examples
≹ Neither Greater-Than Nor Less-Than
- ≹If a ≹ b, then we exclude both a > b and a < b.
- ≹Let x ≹ y under the given ordering restrictions.
- ≹The condition x ≹ y holds when neither strict inequality applies.
- ≹a ≹ a is not permitted by the comparison rule in this system.
- ≹In this definition, ≹ marks cases where there is no strict ordering.

FAQ
How do I type or copy the ≹ symbol?
You can copy it directly from this page. For programming, use the provided code escapes: CSS \\2279, JavaScript \\u{2279}, or HTML entity ≹.
What does ≹ mean in comparisons?
It means “neither greater-than nor less-than,” i.e., you exclude both strict greater-than and strict less-than between two values.
Is ≹ the same as equality?
It’s related but not always identical. In many total-order systems it often implies equality, but interpretation can depend on the ordering rules (especially in partial orders or special-value settings).
Where is ≹ commonly used?
Most often in math and logic expressions, educational notes, formal documentation, and UI/graphics that need a compact “no strict ordering” relation symbol.
