Left Floor Symbol
⌊ is the left “floor” bracket used to denote rounding down in math and logic notation.
U+230A
⌊ is Unicode symbol named LEFT FLOOR (U+230A). It’s commonly paired with ⌋ to form the floor function brackets. You can copy it directly or use its HTML, CSS, or JavaScript escapes.
Left Floor Symbol Meaning
The symbol ⌊ is the left delimiter for the floor function. In mathematics and related technical writing, it appears as part of the pair ⌊ x ⌋, meaning “round down” (toward negative infinity, depending on the convention used). It’s also used in programming, set/interval notation, and explanatory text when describing integer bounds or discretization where values are mapped to an integer by flooring. Because it behaves like a typographic bracket, it’s often selected for readability in formulas and documents, especially in fonts that support Unicode math symbols.
Common uses
- •Write the floor function notation as ⌊x⌋ in math and problem statements
- •Indicate lower integer bounds in algorithm explanations (e.g., “floor of a value”)
- •Format mathematical inequalities and constraints using floor/rounding terms
- •Create consistent typography in technical documents and LaTeX-like text
- •Use as a standalone left delimiter when building custom bracket pairs
Examples
⌊ Left Floor
- ⌊The value is ⌊x⌋, meaning it is rounded down.
- ⌊Compute ⌊n/2⌋ to count complete pairs.
- ⌊We require ⌊y⌋ ≥ 3 for feasibility.
- ⌊The lower bound is given by ⌊a⌋.
- ⌊In proofs, let k = ⌊x⌋.

FAQ
What does the Left Floor symbol mean?
The symbol ⌊ is the left delimiter for the floor function.

What is the Unicode name and code point for ⌊?
⌊ is named LEFT FLOOR and has Unicode code point U+230A.
How do I write the floor function using this symbol?
Typically you use a pair: ⌊x⌋. ⌊ is the left delimiter and ⌋ is the right delimiter.
Can I use ⌊ in HTML or CSS?
Yes. HTML entity: ⌊. CSS escape: \\230A. (Both represent the same character.)
Is ⌊ the same as the normal less-than sign <?
No. ⌊ is a dedicated floor delimiter symbol used in mathematical notation; it is not the same as <.
