Abstract
A method and an apparatus for controlling calculation error produced by the accumulation error due to digit truncation in a non-integer computation. The error is eliminated by controlling the values of LSB, C.sub.in and the addition/subtraction selecting signal as, so that C.sub.in is not necessarily equal to C.sub.in. Considering a even number of cascaded pipelines, C.sub.in in the odd pipelines is set as 0, wherein C.sub.in in the even pipelines is set as 1. The resultant error is thus eliminated mutually by odd and even pipelines.
