Equal and Parallel to

The Equal and Parallel to at U+22D5 is a mathematical relation symbol that combines equality with parallelism, indicating that two objects are being treated as both equal or equivalent and parallel in a stated sense. It is part of the Mathematical Operators block, among specialized symbols for formal relations beyond the basic equals sign and parallel sign. Its real use is narrow and mainly appears in mathematical logic, algebraic notation, geometry, and technical typesetting where an author defines a custom relation. In geometry or vector settings, a statement such as a ⋕ b may be used to say that two directed objects are parallel while also satisfying an equality-like condition specified by the surrounding text. The symbol is not common in standard school mathematics or everyday engineering notation; writers more often spell out “equal and parallel,” use separate symbols, or define their own notation locally. Because it resembles a hash mark crossed with relation strokes, it can be confused visually with number-sign-like symbols or parallel/equality combinations, so its meaning should be defined when used outside a specialized document.
