- The dropping of one or more decimal digits from a number, with the rightmost remaining digit being increased if the next number was 5 or higher. For example, 0.44444 rounded to four decimal places would be 0.4444, while 0.66666 rounded to four decimal places would be 0.6667. When truncating, digits are simply dropped, with the rightmost remaining digit never changing.
- The smoothing of the corners of a rectangular wave or curve with sharp transitions. Seen, for instance, in the comer effect.
