A method of performing an operational expression representing an operation on first and second operands used for computing various problem data and information relating to musical tones, the method comprising the step of representing problem data, which are to be processed, by using a representation system by which the first and second operands have the same sign, and by which the value of one of the first and second operands represented by bits having orders higher than those of bits used for representing the other of the operands is reduced by effecting a suppressing operation by using a suppressing parameter having a value larger than the value that can be obtained by the one of the first and second operands represented by the higher-order bits and the value of which is to be reduced, the step of computing mantissa part data of the thus represented problem data in accordance with power part data of the thus represented problem data, and the step of performing an carry operation if a carry is generated in the mantissa data.
