PURPOSE:To reduce the labor for key input operation by outputting an arithmetic result in a storage means again after or without friction processing when a friction processing form is changed. CONSTITUTION:Change-over switches 2 and 3 are set to 3 and 5/4 and then key operation is carried out in the order of '7, 8, and 9', 'divided by ', '4, 5, and 6', and '=', so that an arithmetic result '1.730' obtained by rounding the 4th digit below the decimal point as the friction processing is displayed after the input numbers '789' and '456' are displayed. Then when the change-over switches 2 is set to 2 without key input, an arithmetic result '1.7303' obtained by rounding the 5th digit below the decimal point as the friction processing is displayed. Further, the change-over switch 2 is changed to F, all digits of the arithmetic result in the arithmetic result holding circuit 8 which can be displayed are displayed as '1.7302631' without the friction processing. |
