U+2309 "⌉" Right Ceiling Unicode Character

U+2309 "⌉" Right Ceiling is a typographical symbol used primarily in mathematical notation to denote the upper limit of a closed interval or to form ceiling brackets that round a real number up to the nearest integer, functioning as the right counterpart to the left ceiling character U+2308. It is part of the Miscellaneous Technical block in Unicode and is often employed alongside its left matching bracket to enclose expressions or values in typesetting systems like LaTeX, where it is typically invoked with the command ceil or \right\rceil. Visually, the character resembles a squared-off corner extending downward from a horizontal top bar, and it should not be confused with similar shaped symbols like the right angle bracket or corner bracket, as its specific use is tied to mathematical floor and ceiling functions.
