U+2A1B "⨛" Integral with Overbar Unicode Character

Unicode Version 17.0

U+2A1B "⨛" Integral with Overbar is a mathematical symbol used primarily in advanced calculus and analysis to denote a specific type of integral where a horizontal bar is placed above the integral sign, often indicating an integration meant to be taken in the sense of a principal value or a particular average, though its precise meaning can vary by context and is not standardized in elementary textbooks. It belongs to the Supplemental Mathematical Operators block and is designed for use in formal mathematical notation, especially in works dealing with functional analysis or measure theory. This character allows typographers and mathematicians to represent a nuanced operator without relying on combining diacritical marks, ensuring clarity in printed and digital mathematical expressions.
