Abstract
PURPOSE: To make it possible to correct input data easily at a halfway point of arithmetic by storing an arithmetic result right before a current arithmetic result and arithmetic assignment inputs used to obtain the result in a series of arithmetic.
CONSTITUTION: Central processor CPU is connected to display unit DIS, display register R1, arithmetic register R2, key-code register EK1 and arithmetic unit ALU via bus BU and through the key operation of keyboard KB, known arithmetic processing is performed. Register R3 and EK2 provided for this invention remembers an arithmetic result right before the current result and an arithmetic assignment code used at that time. When finding an operation error in process of arithmetic, an operator depresses data deletion key DK provided for this invention to shift the contents of registers R3 and EK2 to registers R1 and EK1. As a result, this equipment is placed in a state after the completion of arithmetic one before, thereby making it possible to input correction data.
