upperrange

Upperrange is a term encountered in discussions of ranges and bounds across disciplines. It is not a formal mathematical object in itself, but is commonly used to refer to the upper portion or boundary of a defined set or interval.

In mathematics, the range of a function is the set of its outputs; the upper range is the part of that set near the maximum value. The least upper bound, or supremum, is the smallest value that is greater than or equal to every element of the range. If a dataset has an upper bound M, then M represents an upper range limit, and if M is the least such bound, M is the supremum.

In computing, "upper range" can denote the maximum representable value of a numeric type or the upper end of an input interval used by an algorithm. In statistics, it can refer to the upper tail or upper percentile portion of a distribution. In acoustics or music, it describes higher pitches or the upper register of an instrument or voice.

As a word, "upperrange" is not standardized; most authors write it as two words, "upper range." In product names or branding contexts, it may appear in one word as "UpperRange." See also upper bound, supremum, range, and data range for related concepts.
