Abstract
PURPOSE:To make ease of read of a unit of inputted numeric data, by displaying a character indicating the unit corresponding to a specified digit against a numeric data inputted with the operation of only registering keys. CONSTITUTION:When ''9'' in the 9-th digit is inputted through the operation of an registering key 11a, the operating signal is transmitted to a control section 12. ''9'' is counted on a counter 14. The value ''9'' counted at the counter 14 is given to a decoder 15 and a high level signal is outputted to a one shot circuit 16c via a signal line c from the decoder 15. A pulse is outputted from the circuit 16c, FFs 17a and 17b are reset and an FF17c is set. As a result, a high level signal is inputted to ''100 million and 10 thousand'' terminals of a unit display control section 17, and ''100 million'' is displayed at the 5-th digit of a display 18 and ''10 thousand'' is at the 1st digit. The pulse outputted from the circuit 16c is given to the section 12 via a signal line d. The control section 12 outputs a control signal to a storage section 13 and controls an X register.
