<p><P>PROBLEM TO BE SOLVED: To display past calculation expression and calculation result, without giving discomfort to a user, in multi-replay processing in an electronic calculation expression. <P>SOLUTION: The electronic calculator 1 having a state setting means 25 for setting a computation state of a calculator, and a calculation means 8 for calculation under the computation state set with the input calculation expression, is provided with: a storage means 7 for storing sequentially the input calculation expression, a calculation result in the calculation expression, and data of the computation state set in the calculation, as sets for each calculation, and storing a change command showing that the computation state is changed when the computation state is changed from the computation state set immediately before; a reading instruction means 24 for causing a user to issue a read instruction; and a display means 3 for sequentially reading each set of the calculation expression, calculation result in the calculation expression and data of the computation state, and for displaying change when the computation state is changed when the change command is read. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
