PURPOSE:To correct data so that no contradiction is generated in a result of calculation by providing a rounding error detecting part for detecting a contradiction of a result of calculation caused by a rounding error and a rounding error correcting part. CONSTITUTION:A rounding error detecting part 9 brings an intermediate result of calculation and a final result of calculation to rounding processing, respectively by a data display part 7 and outputs them to a display device 8, and also, detects the end of a calculating operation and executes a recalculation of display data in the display device 8, and detects generation of a rounding error in the display data. In such a way, when a contradiction of a result of calculation is generated, a rounding error correcting part 10 can correct automatically a part of the display data so that no contradiction is generated in a result of calculation. |
