Left Floor ⌊

The Left Floor character (⌊) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ⌊, the decimal numeric character reference ⌊, or the hexadecimal numeric reference ⌊. The character is assigned Unicode code point U+230A in the Universal Character Set.

The left floor bracket (⌊) is the opening bracket of the floor function notation, which rounds a real number down to the nearest integer. The floor function is fundamental in programming (integer division), number theory, and hash function design. Floor brackets look like square brackets with only the bottom corners.

Symbol entities encompass a wide variety of special characters used in legal disclaimers, intellectual property notices, typographic ornaments, card suit indicators, and miscellaneous notation throughout web content. These characters appear in website footers for copyright notices, product pages for trademark symbols, academic papers for dagger footnote markers, and decorative or gaming contexts for card suits and stars.

When deciding how to encode the Left Floor character in your HTML documents, the named entity ⌊ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ⌊ and hexadecimal form ⌊ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the left floor bracket with ⌋ to notate the floor function ⌊x⌋ (largest integer ≤ x) in mathematical and programming content. The floor function corresponds to integer division and truncation in most programming languages and is essential for algorithm analysis.
