PURPOSE:To make a displayed graph easy to see by providing the function which calculates positions of axes of coordinates and measures in accordance with a preliminarily set range of a variable and displays axes of coordinates and measures on a graph display part. CONSTITUTION:A memory part 3 consists of a RAM and has registers 3A-3P. Each data of a functional formula inputted from a key input part 1 is written in an address of a numerical formula buffer 7 indicated by an execution pointer 4 and is read into an calculation part 5. The part 5 uses registers 3A-3P of the memory part 3 to execute the calculation under the control of a control part 2. Data for graph display and display of axes of coordinates and measures are read out from the memory part 3 and are sent to a graph display buffer 6A of a display buffer part 6 when the functional calculation is executed, and data for display of normal numerical values are sent to a text display buffer 6B in case of display of normal numerical values, and a graph or numerical values or the like are displayed. |
