PROBLEM TO BE SOLVED: To provide a multiple arithmetic circuit on the premise of judging whether or not an optional calculated value is an integral multiple of 5, with small circuit scale, by simple circuit structure and capable of realizing cost reduction and a high speed operation. SOLUTION: Whether or not a coordinate value is the integral multiple of 5 is judged by sectioning the coordinate value into the respective bit columns of four bit by a section setting part 109, calculating the total sum of values of the respective bit columns by an adding circuit 110 and collating the total sum with the respective preset multiples by a decoder part 111. |
