Abstract

PURPOSE:To know the number of data shunting registers that are used presently for a small-size electronic calculator which performs the multiplication/division in preference to the addition/substraction, by displaying the using condition of the data shunting register through an operation of a specified key. CONSTITUTION:With operation of a key, the key input part 10 transmits the corresponding signal to the operation control part 11. When the control part 11 decides a necessity of shunt for the midway result with operation of both the multiplication and division keys of the part 10, the signal 101 is transmitted to the inputs of the OR gate 14 and AND gate 72. With operation of the SP key, the signal 105 is transmitted to the inverter 16 and AND gate 18 from the part 11. Thus a switching is given between the data of the register 21 and the information data of the shunting register monitor signal generating circuit for a display 12. Thus the using condition of the data shunting register is displayed with operation of the SP key to know the number of shunting registers that are used presently.
