An electronic apparatus provided with a device of calculating complex numbers includes a keyboard for entering calculation data including a value and an imaginary number unit i, an LCD device for displaying a result of performed calculation of the complex numbers consisting of a real number and an imaginary number unit i, and a processing unit. The processing unit has a judging part for judging whether or not a value is entered immediately before or after the imaginary number unit i, first calculating part for calculating the complex numbers in accordance with a predetermined priority in calculation by substituting 1i with the imaginary number unit i while inserting a multiplication code between the entered value and the imaginary number unit i upon detecting the entered value is positioned before the entered imaginary number unit i, and second calculating part for calculating a portion having the imaginary number unit i as a function followed by an argument upon detecting calculation data that a value is entered immediately after the imaginary number unit i.
