rounding Replacing a number by another number having fewer The error accumulated during a calculation due to significant digits or, for integer numbers, fewer value-carrying (non-zero) digits. For example, 386.804 may be rounded successively to 386.80, 386.8, 387.390, and 400. Rounding may be carried out in two ways: by rounding down, which is equivalent to truncation, and by rounding up the last digit to be retained by one unit.
