Circled Dot Operator (⊙) is the Unicode character at U+2299 in the Mathematical Operators block (official name: CIRCLED DOT OPERATOR). It shows a dot inside a circle and appears in math notation (including some Hadamard-style or element-wise product contexts).
Remember
Character ⊙
Unicode U+2299
Hex entity ⊙
Decimal ⊙
Named entity ⊙
CSS escape \2299
All of these produce the same glyph: ⊙. Prefer ⊙ or a typed ⊙ in hand-written HTML; use numeric forms when generating markup.

Use ⊙ (hex), ⊙ (decimal), ⊙ (named), or the CSS escape \2299 in the content property. All render ⊙. You can also paste ⊙ directly when your file is UTF-8.
U+2299 (hex 2299, decimal 8857). Unicode names it CIRCLED DOT OPERATOR. It belongs to the Mathematical Operators block.
Yes. ⊙ maps to U+2299. Prefer ⊙ in hand-written HTML; numeric forms are useful in generated markup.
⊙ (U+2299) is circled dot operator. ⋅ (U+22C5) is the plain dot operator. • (U+2022) is bullet — used for lists, not as a circled math operator.
HTML entities (⊙, ⊙, or ⊙) go in markup. The CSS escape \2299 is used in stylesheets (usually in the content property of ::before/::after). Both render ⊙.
Use it in math or linear algebra when you need this exact circled-dot operator (for example some Hadamard-style notations). Prefer ⋅ or a middle dot for ordinary multiplication dots.
