Abstract
PURPOSE: To make it possible to determine any strict error within a fixed range by finding value R0 approximate to the reciprocal number of divisor D for a division process between dividend N and divisor D.
CONSTITUTION: Approximate value R0 of the reciprocal of divisor D is found and approximate value R1 of the reciprocal of the product of divisor D and approximate value R0 is also found; and approximate value Ri+1 of the reciprocal of the product of D and approximate values R0WRi is similarly obtained. Then, approximate values R0WRn obtained in the above-mentioned way are processed according to (formula-A) and after the process is repeated fixed times until fixed error precision is obtained, expedient quotient Qn is obtained. Next, quotient Qn is rounded and under the condition the obtained remainder satisfies, corrections are made. This arithmetic is attained by a unit composed of normalization circuit parts 1 and 7, size-comparison and fine-adjustment processing part 2, R0 index table, multiplier 4, digit-matching processing part 5, adder 6, buffer or bus 8, and registers 9W16.
