About the right ceiling symbol

In mathematical typesetting, the right ceiling symbol forms the right side of a ceiling bracket, paired with its left counterpart to enclose an expression or value. It is part of the notation for the ceiling function, which rounds a real number up to the nearest integer, and appears in computer science, engineering, and mathematics texts. As a close punctuation character in the Miscellaneous Technical block, it is also found in technical diagrams and notation systems where paired brackets are required.
