Integral With Overbar Symbol
⨛ denotes an integral sign with an overbar for specialized mathematical notation.
U+2A1B
⨛ is the “Integral with Overbar” symbol, used in advanced math typesetting. It can appear in formal writing, equations, and technical documents where an overbar modifies the integral notation.
Integral With Overbar Symbol Meaning
The symbol ⨛ is “INTEGRAL WITH OVERBAR” (Unicode U+2A1B). In mathematical notation, an overbar above an integral sign typically indicates a variation of the standard integral—commonly related to averaging, modified integration conventions, or specific operator definitions used in a given text or field. Because the exact interpretation can depend on context (for example, the definitions in a textbook or the surrounding formula), it’s best to pair ⨛ with the notation used by your source. When you copy it into equations, ensure your font and math rendering support Unicode U+2A1B.
Common uses
- •Represent a modified or specialized integral operator in math notes and lecture slides
- •Write formal equations in academic documents where an overbar changes the integral’s meaning
- •Label expressions in textbooks or research papers that define a custom integral notation
- •Create consistent symbols in equation editors for technical diagrams and reports
- •Use in digital typography to match published mathematical notation
