What Is the Neither Approximately Nor Actually Equal To Entity?
Neither approximately nor actually equal to (≇) is the Mathematical Operators character at Unicode U+2247 (NEITHER APPROXIMATELY NOR ACTUALLY EQUAL TO). It is the negation of ≅ (≅, approximately equal to). HTML5 provides the named entity ≇.
Remember
Character ≇
Unicode U+2247
Named entity ≇
Hex entity ≇
Decimal ≇
CSS escape \2247
All of these produce the same glyph: ≇. Prefer ≇ for readable HTML; paste ≇ in UTF-8 when convenient.

How It Works
1. Named:≇ is the clearest HTML form for U+2247.
2. Hex:U+2247 → ≇ in HTML. Reliable numeric form.
3. Decimal: same code point as 8775 → ≇. Same glyph.
4. Direct: paste ≇ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \2247 in content (not an HTML entity). #point::after appends that ≇ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with this mathematical entity.
Meaning
Negates ≅, not ≠
≇ is “notcong”. For general inequality use ≠ (≠).
Named
Prefer ≇
The named form is easier to read than hex or decimal in math markup.
CSS vs HTML
Do not mix escapes
\2247 belongs in CSS. ≇ / ≇ / ≇ belong in HTML.
Look-alikes
Not ≅, ≈, or ≠
≅ is cong; ≈ is approx; ≠ is not equal. Different symbols with different meanings.
Semicolon
End references
Always finish with ; — write ≇, not &ncong.
UTF-8
Declare charset
If you paste ≇ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
Neither approximately nor actually equal to (U+2247) and its entity forms (≇, ≇, ≇, CSS \\2247) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Neither Approximately Nor Actually Equal To (≇)
Prefer ≇, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer ≇ in HTML. Use ≇ / ≇ when a numeric form is required, and \\2247 only inside CSS content.

Key Takeaways
Unicode: notcong is U+2247 (decimal 8775), Mathematical Operators.
Use ≇ (named), ≇ (hex), ≇ (decimal), type ≇ in UTF-8, or the CSS escape \2247 in content. All render ≇.
U+2247 (NEITHER APPROXIMATELY NOR ACTUALLY EQUAL TO). Hex 2247, decimal 8775. It belongs to Mathematical Operators and is the negation of ≅ (approximately equal to).
Yes. HTML5 defines ≇ for this character. You can also use ≇ or ≇.
Use it in math or science when two values are not approximately/congruently equal (A ≇ B). Prefer ≇ for readable source. For ordinary English, write the relation in words.
HTML entities (≇, ≇, or ≇) go in markup. The CSS escape \2247 is used in stylesheets (usually in the content property of ::before/::after). Both render ≇.
≅ (U+2245, ≅) means approximately equal to. ≈ (U+2248, ≈) is another approximate-equality sign. ≠ (U+2260, ≠) means not equal to. ≇ specifically negates ≅. Do not substitute one for another.
🤔
Did you know?
Neither approximately nor actually equal to (≇) is Unicode U+2247 (decimal 8775) — NEITHER APPROXIMATELY NOR ACTUALLY EQUAL TO in Mathematical Operators. HTML5 provides ≇. It negates ≅ (≅, approximately equal to). Use it when values are neither congruent/approximately equal nor exactly equal in the intended sense.
