Formula examples
A⊙BHow to type Circled Dot Operator
- Windows
- Use Character Map or enter U+2299 in a Unicode-aware application.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type \odot and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ⊙, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ⊙, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ⊙ or use Insert → Special characters. For structured math, use the equation editor and verify \odot.
- Excel
- Paste ⊙ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Preserve grouping, operator order, and spacing around ⊙; Define whether the symbol means a Hadamard product, circular operation, or another local convention.
- For plain text, copy ⊙ as U+2299; for structured equations, use \odot in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Circled Dot Operator.
When to use ⊙
- Use ⊙ in plain text when a Unicode character is appropriate and the destination preserves U+2299.
- Use \odot in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Circled Dot Operator is used in functions operators, linear algebra with a field-specific convention.
