(engineering) a measurement of deviation from circularity of an oval or approximately elliptical shape.
The quality of being round; rotundity.
In telecommunications and fiber optics, ovality or noncircularity is the degree of deviation from perfect circularity of the cross section of the core or cladding of the fiber. The cross-sections of the core and cladding are assumed to a first approximation to be elliptical.
The quality or state of being round in shape; as, the roundness of the globe, of the orb of the sun, of a ball, of a bowl, a column, etc.
Fullness; smoothness of flow; as, the roundness of a period; the roundness of a note; roundness of tone.
Openess; plainess; boldness; positiveness; as, the roundness of an assertion.
the property possessed by a line or surface that is curved and not angular
Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing.
