Not Almost Equal To Symbol
≉ means “not almost equal to,” used to show two quantities are not approximately the same.
U+2249
The symbol ≉ is a mathematical comparison sign. It’s commonly used in contexts where “almost equal” would normally indicate approximate equality, but here that approximation does not hold. You can copy it directly or use the provided codepoint and escape sequences.
Not Almost Equal To Symbol Meaning
≉ is the Unicode symbol named “NOT ALMOST EQUAL TO” (U+2249). It is used in mathematical writing to state that two values are not approximately equal. In practice, this helps distinguish strict inequality from the specific idea of “almost equal,” which is often used with tolerances or approximations. For example, two numbers might be close but still not within the chosen “almost” threshold; ≉ communicates that the approximation does not qualify as almost equal. When you need a clear “not approximately equal” comparison in equations, notes, or technical text, ≉ is the appropriate symbol.
Common uses
- •Marking approximate comparisons in equations where the tolerance condition fails
- •Writing technical notes that contrast “almost equal to” with “not almost equal to”
- •Labeling axes or annotations in math/engineering diagrams for non-matching approximations
- •Indicating inequality in proofs or comparisons that rely on approximation rules
- •Formatting documentation text for calculations that should not be treated as approximately equal
Examples
≉ Not Almost Equal To Symbol
- ≉a ≉ b because they differ beyond the allowed tolerance.
- ≉f(x) ≉ f(y) for the given approximation criterion.
- ≉The result is ≉ the expected value at this scale.
- ≉Using this model, the measured quantities are ≉ each other.
- ≉Check that x ≉ y before applying the approximation step.
