MULTIPLIER APPARATUS AND METHOD FOR REAL OR COMPLEX NUMBERS

A multiplier for real or complex numbers is split at each data input into two equally large digit ranges to determine partial products in separate subfields. Within a rectangular partial-product field, the subfields are rearranged according to the real or complex arithmetic operation to be performed, the rearrangement being effected by assigning basic weights to the individual subfields. By means of an adding arrangement, the partial products of the individuals subfields are added in a positionally correct manner to form the digits of a real or complex output number.
