Abstract
A fractional arithmetic unit for performing fractional arithmetic operations of different numerators and a common denominator with different precisions as required, the fractional arithmetic unit, including a reciprocal number arithmetic logic unit; and a multiply arithmetic circuit configured to multiply a numerator and a reciprocal number of the denominator as obtained by the reciprocal number arithmetic logic unit. A precision of a calculation performed by the reciprocal number arithmetic logic unit is changed in accordance with a precision as required for each of the fractional arithmetic operations. The multiply arithmetic circuit outputs a result of multiplication as a result of the fractional arithmetic operation, and the results of the fractional arithmetic operations are output with different precisions.
