Arrotondatura

Arrotondatura is a term that can be found in some Italian-language texts as a noun derived from the verb arrotondare, meaning the act or result of rounding a shape or value. The suffix -tura forms a noun indicating a process or state, but in practice the more common form is arrotondamento. As a result, arrotondatura appears mainly in specialized, stylistic, or regional usage rather than standard technical writing.

In mathematics, statistics, and computing, arrotondatura may refer to the practice of rounding numbers to a specified precision or to rounding coordinates and geometric data. It can also denote the quality or nature of a figure whose edges are smoothed into curves, as opposed to having sharp corners. The specific rounding rule (for example, rounding up, down, or to the nearest value) is typically described separately from the term itself.

In design, architecture, and manufacturing contexts, the word is used informally to describe objects with smoothly curved, non-sharp edges or corners. An item described as having an “arrotondatura” would be noted for its rounded profile, which can affect aesthetics, ergonomics, and safety. Because arrotondatura is less common in formal documentation, readers often encounter the standard term arrotondamento in technical texts.

Notes: arrotondamento is the preferred Italian term for rounding; arrotondatura appears sporadically and is not widely used in formal literature. Related concepts include rounding, curvature, and geometric smoothing.
