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.
A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirement Document PRD. Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system level, on the module level and on the level of technical details.
