Abstract

PURPOSE:To quickly calculate the quotient without error, by constituting a dividing device with a multiplying means, a rounding means, a partial dividing means and a quotient means respectively. CONSTITUTION:Both a dividend N and the output of a multiplying circuit 3 are supplied to a partial residue register 1; a divisor D and the output of the circuit 3 are supplied to a correcting divisor register 2; and the outputs of the registers 1 and 2 are selectively supplied to the circuit 3. A part of the output of the register 2 is supplied to a reciprocal number table memory 4; the output of a multiplier register 5 is supplied to a partial quotient register 6; and the outputs of the registers 6 and 5 are supplied to a quotient correcting circuit 7 respectively.
