Abstract
An arithmetic division for implementation using hardware or software is performed by firstly storing the reciprocal of each nth value in a range 0 to X where n is greater than 1 and storing the differences between the reciprocals of the intervening n-1 values. A mantissa and an operand for an arithmetic division are received. one of the stored reciprocals is retrieved in response to the most significant part of the received mantissa and a set of differences is retrieved in response to a least significant part of the received mantissa. The differences and the reciprocal are summed and the result is multiplied by the received operand, other thereby giving the result of the arithmetic division.
