ABSTRACT:
There is disclosed a multiplier having a digit rounding function which operates by selecting an added value for rounding a digit in the process of adding partial products, thereby reducing a circuit magnitude and realizing a high-speed operation. A multiplier 13 is provided with selection circuits 18, 19 and 1A which can switch values of the partial products obtained in a secondary Booth algorithm in response to a signal for controlling the presence of the digit rounding function.
