Abstract
A circuit for shifting the bits of an X word to obtain a Y word which is rounded to the nearest odd integer if any bit having the value 1 was shifted off of the word during the shifting operation. The circuit avoids biasing in the integer rounding operation. The shifting operations are accomplished with the aid of multiplexing circuits. The rounding operation is accomplished with the aid of multiplexing circuits that connect the least significant bit of Y to (X.sub.0 OR X.sub.1 OR . . . X.sub.m), where m is the number of places by which X is shifted.
