Definition

What Is the Up Right Diagonal Ellipsis Entity?

Up Right Diagonal Ellipsis (⋰) is the Unicode character at U+22F0 (UP RIGHT DIAGONAL ELLIPSIS) in Mathematical Operators. It is three dots arranged diagonally up and to the right — used to show continuation or omission in matrices and sequences.

Remember

Character     ⋰
Unicode       U+22F0
Hex entity    &#x22F0;
Decimal       &#8944;
Named entity  &utdot;
CSS escape    \22F0
Not the same  &dtdot; (⋱) · &cdots; (⋯)

All of these produce the same glyph: ⋰. Prefer &utdot; in HTML for readable math markup. For ordinary prose “…” use ….

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`&utdot;`	HTML markup (preferred)
Hex entity	`⋰`	HTML markup
Decimal entity	`⋰`	HTML markup
Direct character	`⋰`	UTF-8 HTML text
CSS escape	`\22F0`	Stylesheet `content`

When to Use Which

Situation	Use
Readable up-right diagonal dots in HTML	`&utdot;`
Need a numeric entity	`⋰` or `⋰`
Generated text via `::before` / `::after`	`content: "\22F0"`
Down-right diagonal dots	Use `&dtdot;` (U+22F1)
Midline horizontal math dots	Use `&cdots;` (U+22EF)

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">

  <style>
    #point::after {
      content: "\22F0";
    }
  </style>

  <p>Typed directly: &#x22F0;</p>

Try It Yourself

How It Works

1. Hex: U+22F0 → ⋰ in HTML. The browser turns it into the glyph.

2. Decimal: same code point as 8944 → ⋰. Same result as hex.

3. Named: &utdot; is the HTML5 name for U+22F0. Easiest to read in source.

4. CSS: use \22F0 in content (not an HTML entity). #point::after appends that glyph after the paragraph text.

5. Matrix line: a₁₁ &utdot; a_nn shows a typical diagonal-continuation pattern.

Pitfalls & Tips

Common mistakes when working with this ellipsis.

Look-alikes

Direction matters

&utdot; is up-right. &dtdot; is down-right. &cdots; is midline horizontal. Do not swap them.

Prose

Not for sentence ellipsis

For ordinary “…” in text, use … (U+2026). Reserve &utdot; for math notation.

CSS vs HTML

Do not mix escapes

\22F0 belongs in CSS. &utdot; / ⋰ / ⋰ belong in HTML.

Fonts

Check the glyph

Mathematical Operators coverage varies. If the mark is missing, describe the omission in nearby text.

A11y

Do not rely on the dots alone

Screen readers may not explain diagonal ellipsis clearly. Keep surrounding math labels readable.

Semicolon

End references

Always finish with ; — write &utdot;, not &utdot.

Compatibility

Browser Support

Up Right Diagonal Ellipsis (U+22F0) and its entity forms (&utdot;, ⋰, ⋰, CSS \\22F0) are supported in all mainstream browsers. Glyph shape depends on the font.

✓ Universal support

Bottom line: Prefer &utdot; in HTML for readable math source. Use \\22F0 only inside CSS content. Prefer … for prose ellipsis.

Remember

Key Takeaways

Unicode: this symbol is U+22F0 (decimal 8944).
HTML: prefer &utdot; (or ⋰ / ⋰).
CSS: use \22F0 inside content for generated text.
Watch out: &utdot; ≠ &dtdot; ≠ &cdots;.

One line: U+22F0 → &utdot; / ⋰ / ⋰ / CSS \22F0.

Frequently Asked Questions

How do I display Up Right Diagonal Ellipsis in HTML?

Use &utdot; (named), ⋰ (hex), ⋰ (decimal), or the CSS escape \22F0 in the content property. All render U+22F0. You can also paste the character directly when your file is UTF-8.

What is the Unicode value for Up Right Diagonal Ellipsis?

U+22F0 (hex 22F0, decimal 8944). Unicode names it UP RIGHT DIAGONAL ELLIPSIS. It belongs to Mathematical Operators (U+2200–U+22FF).

Is there a named HTML entity for U+22F0?

Yes. &utdot; is the HTML5 named entity. You can also use ⋰ or ⋰.

How is &utdot; different from &dtdot; and &cdots;?

&utdot; (U+22F0) is three dots diagonally up-right. &dtdot; (U+22F1) is diagonally down-right. &cdots; (U+22EF) is a midline horizontal ellipsis. They are different code points.

What is the difference between HTML code and CSS entity for U+22F0?

HTML entities (&utdot;, ⋰, or ⋰) go in markup. The CSS escape \22F0 is used in stylesheets (usually in the content property of ::before/::after). Both render the same glyph.

When should I use this symbol?

Use it in matrix, sequence, or set notation to show continuation along an up-right diagonal. Prefer … for ordinary prose ellipsis. Always keep nearby math labels for accessibility.

Did you know?

This symbol is Unicode U+22F0 (decimal 8944) — official name UP RIGHT DIAGONAL ELLIPSIS in Mathematical Operators. HTML5 names it &utdot;. It differs from &dtdot; (down-right, U+22F1) and &cdots; (midline horizontal, U+22EF).
