Left Ceiling ⌈

The Left Ceiling 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+2308 in the Universal Character Set.

The left ceiling bracket (⌈) is the opening bracket of the ceiling function notation, which rounds a real number up to the nearest integer. The ceiling function is fundamental in computer science for array sizing, pagination, and discrete mathematics. Ceiling brackets look like square brackets with only the top 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 Ceiling 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 ceiling bracket with ⌉ to notate the ceiling function ⌈x⌉ (smallest integer ≥ x) in mathematical and computer science content. The ceiling function is essential for calculating array sizes, page counts, and discrete allocations from continuous values.
