Neither Approximately Nor Actually Equal To Symbol
≇ denotes that two quantities are neither approximately equal nor exactly equal.
U+2247
The symbol ≇ is a math operator used to express strong “not equal” relationships. It’s commonly seen in technical writing, formulas, and typeset documents. Use it when you want to rule out both approximate and exact equality.
Neither Approximately Nor Actually Equal To Symbol Meaning
≇ (U+2247) stands for “NEITHER APPROXIMATELY NOR ACTUALLY EQUAL TO.” In mathematical contexts, it communicates that one quantity is not equal to another in both senses: they are not approximately the same and also not exactly equal. This is stronger than symbols that only indicate approximate inequality. People use ≇ when accuracy matters, such as comparing measured values, stating that an approximation is invalid, or clarifying that a statement of equality does not hold even approximately.
Common uses
- •Stating that two expressions are not approximately equal and not exactly equal
- •Formally rejecting an approximation or estimate in technical documents
- •Writing conditions for proofs or derivations where equality must fail
- •Annotating datasets or measurements to indicate mismatch beyond approximation
- •Creating clear UI or documentation labels for “not equal” validation rules
Examples
≇ Neither approximately nor actually equal to
- ≇a ≇ b
- ≇x ≇ y (not even approximately equal)
- ≇f(n) ≇ g(n)
- ≇The values are ≇ under the given tolerance.
- ≇p ≇ q, so the equation does not hold.

FAQ
What does the symbol ≇ mean?
≇ means “neither approximately nor actually equal to,” indicating the values are not equal even approximately.
Is ≇ different from ≠ (not equal to)?
Yes. ≠ generally indicates not exactly equal, while ≇ also explicitly rejects approximate equality.
How do I copy ≇ for use in HTML?
You can use the HTML entity: ≇.
How do I include ≇ in CSS or JavaScript?
CSS escape: \\2247. JavaScript (Unicode escape): \\u{2247}.
