Abstract
PURPOSE: To eliminate the need for a switch and key dedicated to decimal-point position assignment, by making it possible to assign the decimal point position according to the frequency of the depression of numeric keys following a specific key when the specific key is depressed twice continuously.
CONSTITUTION: To display the arithmetic result of 1÷3, for example, down to the 3rd decimal point, numeric key NK1 is pushed, the decimal point key is depressed twice continuously and then key NKO is operated three times. Consequently, while counter DP1 counts up to three, display unit DIS displays 1.000. Next, the ÷ key, "3" key and = key are pushed successively to perform division. On the basis of the control signal from CPU, the decimal point position of arithmetic result 0.33333... is matched with data 3 in register DPR, so that register R1 will have 0.333. Then, 0.333 is displayed on unit DIS under the control of CPU.
