摘要
A compact calculator includes a matrix type display unit and executes a graphic representation of a functional formula. When both the functional formula and an integral range are inputted as information about a definite integral, a judgement is done whether or not an X-value increased while forming a graphic representation is located with the integral range. If this X-value is present within the integral range, then the pixels from the coordinate point (X,Y) to an X-axis are turned on. Thus, the integral range is graphically represented under the above- described process operation.
