The maps to symbol, ↦, is a rightward arrow protruding from a vertical bar. It is used in mathematics and in computer science to denote functions.In Z notation, a specification language used in software development, [1] this symbol is called the maplet arrow and the expression x ↦ y is called a maplet.
An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction.

It is akin to an arrow in the cylindrical coordinate system. A cylindrical vector is specified by a distance in the xy -plane, an angle, and a distance from the xy -plane (a height). The first distance, usually represented as r or ρ (the Greek letter rho ), is the magnitude of the projection of the vector onto the xy -plane.
A vinculum (from Latin vinculum 'fetter, chain, tie') is a horizontal line used in mathematical notation for various purposes. It may be placed as an overline or underline above or below a mathematical expression to group the expression's elements.
