. Rounds were popular in 17th-century England when the catch reached its height. The catch was originally just a simple round, e.g., Three Blind Mice, written in a single line with the effect gained by having another singer come in ("make the catch") at the right time. Later, comic effects, often quite bawdy, were added, using the interweaving of the parts. The Rounds, Catches and Canons of England (1864) by E. F. Rimbault is a comprehensive collection. The term round was also used to designate a dance performed in a circle and, by extension, to the tunes for such dances.

To eliminate rightmost digits in a number when absolute precision is not required or used. One of the most common uses of rounding is with dollar amounts, which can result in more than two decimal places after a division. Following are four of many rounding methods:

  Round Half Up    3.455 -> 3.46
                   3.454 -> 3.45

  Round Half Down  3.455 -> 3.45
                   3.456 -> 3.46

  Round Up         3.456 -> 3.46
                   3.453 -> 3.46

  Round Down       3.458 -> 3.45
                   3.453 -> 3.45

He looked round the broad ashen path on which the race was to be run, conscious that he had a secret interest in it which it was unutterably repugnant to him to feel.
"How many times must they go round this inclosure," he inquired, "before the race is ended?"
"The path measures four hundred and forty yards round," he said, when the surgeon had repeated Sir Patrick's question to him.
