The adder 11 performs addition of A+B+C+1, and the adder 10 performs addition of A+B+C. An inverting circuit 15 takes the addition value of the adder 10 as the input and inverts its value to output the result. A selecting circuit 13 selects the output of the inverting circuit 15 as the one's complement of A+B+C and outputs this output as a fixed-point part addition result 3. A sign calculating circuit 14 outputs the sign part addition result of the negative sign because only data C0 is positive and the last carry is 0.
