PURPOSE:To know a mode from a printed result and to facilitate a check on the process of calculation, by printing a newly set mode every time the mode is changed. CONSTITUTION:A CPU is a control part for outputting pieces of arithmetic, display, and printed information and the CPU is controlled by an input from a keyboard KEY to display the information at a display part DISP while printing the data on a printer PRT through a printer control circuit PCU. For example, when a key ''STAT'' is pressed twice successively, ''STAT'' or ''COMP'' is printed to indicate a statistic calculation mode ''STAT'' or normal calculation mode ''COMP''. When a key ''DRG'' is pressed three times successively, ''RAD'', ''GRAD'', and ''DEG'' are printed to indicate an RAD mode, GRAD mode, and DEG mode. Consequently, modes are known in the process of calculation to facilitate a check. |
