## roundingReplacing 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. ## Related entry• banker's rounding## Related category• APPROXIMATIONS AND AVERAGES | |||||
