ABSTRACT:
This invention relates to apparatus for obtaining the numerical value of a function of a single or plural number of variables. The method of cascade accumulation is used in which memories M0, M1, M2, . . . , Mn are involved and under one cycle of manipulation the contents of memories M1, M2, . . . , Mn are added to the contents of M0, M1, M2, . . . , Mn-1 respectively. By loading a digital value determined by a.sub.0, a.sub.1, a.sub.2, . . . , a.sub.n into each of the memories as its initial value and repeating x cycles of the above mentioned manipulations, the digital value of the function
