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.
Functional requirements are often modeled wih the aid of use-cases and scenarios, while the analysis step starts to identify some of the candidate objects / classes that will be needed in the system.
