Abstract
A portable electronic computer or calculator is characterized in that it calculates a functional operation on the previously calculated result by simply actuating a function key switch while the result is being displayed. It is unnecessary to actuate any entry key switch. In a specific form of the present invention, the computer may calculate a functional operation on numerical data in response to input of a function command, the numerical data being either newly inputted or previously calculated.
