- ⌋ — Right Floor Bracket
Use ⌊ in the right format
Meaning and usage
Begins floor notation, which rounds a real number down to the greatest integer not exceeding it.
Pair it with a right floor bracket around the complete argument.
Pronunciation: left floor bracket
Formula examples
⌊xHow to type Left Floor Bracket
- Windows
- Use Character Map or enter U+230A 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 \lfloor 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 \lfloor.
- 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 ⌊; Pair it with a right floor bracket around the complete argument.
- For plain text, copy ⌊ as U+230A; for structured equations, use \lfloor in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Left Floor Bracket.
When to use ⌊
- Use ⌊ in plain text when a Unicode character is appropriate and the destination preserves U+230A.
- Use \lfloor in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Left Floor Bracket is used in functions operators, number theory with a field-specific convention.
