PROBLEM TO BE SOLVED: To easily discover the unit of the cell of a table or the error of the formula of calculation between cells. SOLUTION: This system includes a cell formula preserving part 110 which preserves an inputted calculation formula, a cell information unit preserving part 120 which preserves the unit of the numeric of the inputted cell, a parameter mutual validity verifying and judging part 130 which judges whether or not it is necessary to make the same the units of the numerics to be calculated in the formula, a parameter mutual validity verifying part 140 which judges whether or not the units of the numerics of the designated cells are the same, a calculated result unit calculation processing part 150 which calculates the unit of the result of the designated formula, calculated result validity verification processing part 160 which judges whether or not the units of the two kinds of designated numerics are the same, and a cell status preserving part 170 which preserves the state of the validity of the formula preserved in the cell. |
