Abstract
A multiplication or division operation X·K or X·1/K is performed in an electronic circuit. A software circuit area of the circuit calculates a digit shift sv such that pis an approximate value for K. In a hardware circuit area, the value X is shifted sv digits to the left in the case of multiplication or sv digits to the right in the case of division. The software circuit area calculates a suitable correction factor Kf. The value X is multiplied by the correction factor Kf.
