The most common character corresponding to an ellipsis is called 3-ten rÄ«dÄ (3-dot leaders, â¦). 2-ten rÄ«dÄ exists as a character, but it is used less commonly. In writing, the ellipsis consists usually of six dots (two 3-ten rÄ«dÄ characters, â¦â¦).
In software engineering (and systems engineering), a functional requirement defines a function of a system and its components.
The documentation typically describes what is needed by the system user as well as requested properties of inputs and outputs (e.g. of the software system). A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirement Document PRD.
