Integral With Union Symbol
⨚ (Integral with Union) is a mathematical symbol that combines an integral sign with a union operator.
U+2A1A
The symbol ⨚ is known as the Integral with Union. It’s used in math writing when an integral interacts with a union-style set operation. This page helps you understand and copy it for documents, typesetting, and code.
Integral With Union Symbol Meaning
⨚ is the “Integral with Union” symbol (Unicode U+2A1A, html entity ⨚). In mathematical notation, it represents an integral together with a union operator, suggesting a construction where you integrate over a combined set or an expression indexed by unions of sets. Like many specialized Unicode math symbols, it’s most common in formal writing, technical documentation, and rendered mathematical text where authors need a compact combined operator. When you use it in plain text, it may depend on font support; in web contexts, using the Unicode code point ensures consistent rendering where supported.
Common uses
- •Writing set-based integral expressions that involve unions of domains
- •Formatting technical notes and lecture materials for mathematics
- •Labeling or describing operations in papers and reports
- •Using Unicode math symbols in digital documents and slide decks
- •Including the character in web content or code samples for math typesetting
