Etymology
the word 'rounding' is built upon the old english adjective 'rund', which conveyed the sense of something circular or spherical. this concept of circularity naturally extended to the idea of completeness or wholeness. the addition of the noun-forming suffix '-ing' transforms the action of the verb 'to round'—meaning to make circular or to complete—into a noun denoting the process or result. in its primary modern mathematical sense, 'rounding' metaphorically applies this idea of completion, bringing a number to a neater, more 'whole' or simplified value.
