摘要：
There is provided a scaling operator for calculating a quotient in a first residue format obtained by dividing an input number in the first residue format by a second modulus in a residue number system for representing numbers by the first residue format of a set of residues obtained with respect to first modulus and residues obtained with respect to second modulus, having a subtracter for outputting inter-moduli values of difference which are values of difference between the residues obtained with respect to the first modulus and the residues obtained with respect to the second modulus and a quotient outputting section for outputting a set of residues of the quotient obtained with respect to the first modulus and residues of the quotient obtained with respect to the second modulus as the quotient based on the inter-moduli values of difference.
