Another meaning of range in computer science is an alternative to iterator. When used in this sense, range is defined as "a pair of begin/end iterators packed together". [1] It is argued [1] that "Ranges are a superior abstraction" (compared to iterators) for several reasons, including better safety.
Sometimes "range" refers to the image and sometimes to the codomain. In mathematics, the range of a function may refer to either of two closely related concepts: the codomain of the function, or; the image of the function. In some cases the codomain and the image of a function are the same set; such a function is called surjective or onto.
Range reduction (also argument reduction, domain-spltting) is the first step for any function, after checks for unusual values (infinity and NaN) are performed.The goal here is to reduce the domain of the argument for the polynomial to process, using the function's symmetry and periodicity (if any), setting flags to indicate e.g. whether to negate the result in the end (if needed).

atan2(y, x) returns the angle θ between the positive x-axis and the ray from the origin to the point (x, y), confined to (−π, π].Graph of (,) over /. In computing and mathematics, the function atan2 is the 2-argument arctangent.
The essential range satisfies : (). = =. This fact characterises the essential image: It is the smallest closed subset of C {\displaystyle \mathbb {C} } with this property. The essential supremum of a real valued function equals the supremum of its essential image and the essential infimum equals the infimum of its essential range.
