Arredondado

Arredondado is a Portuguese adjective and the past participle of the verb arredondar. It describes something that has been made round or curved, or a value that has been approximated to a nearby quantity. The term is widely used in geometry, design, mathematics, and everyday language.

Etymology and senses: Arredondar comes from redondo (round) with the prefix ar-, indicating the action of making round. Arredondado thus refers to both physical shapes with curved edges and to numerical results that have undergone rounding. The corresponding noun is arredondamento, referring to the process of rounding.

Usage in geometry and design: In describing objects, arredondado denotes shapes with smooth, curved corners or edges, such as cantos arredondados or bordas arredondadas. This contrasts with sharp-edged or angular forms. In typography, architecture, and product design, rounded forms are often described as arredondadas to emphasize softness or safety.

Usage in mathematics and computing: In math and computing, arredondado refers to numbers that have been approximated to a specified precision. Common phrases include arredondado para duas casas decimais (rounded to two decimal places) or arredondar para o inteiro mais próximo (round to the nearest integer). Different rounding methods exist, such as arredondamento para cima (ceiling), arredondamento para baixo (floor), and arredondamento convencional (round half up).
