Abstract

PURPOSE: To ensure an extremely easy reading of the numerical value shown in many digits, by displaying the positional notation mark concerning the effective figures via the higher-rank digit unnecessary suppression signal with no display of the positional notation mark concerning the ineffective zero of the higher-rank digit each in case the displayed numerical value is an integer.
CONSTITUTION: The digit outputs LSD, 2D, 3D, 4D, 5D and MSD of the 1st output driving part DR plus the decimal point position display information DP1WDP6 about each digit of the 2nd output driving part DPR are supplied to each digit display position of the display part DIS. At the same time, the outputs DP1 and 4D are supplied to the AND gate G1, and the outputs DP1 and 5D are supplied to the AND circuit G2 each. Here the outputs of the circuits G1 and G2 are used for the display signals of "1,000" and "10,000" of the display part DIS respectively. The higher-rank digit unnecessary suppression signal is supplied to the part DR from the CPU in the form of the F code of the decimal 4-bit 1111 and others, thus deciding the ineffectiveness of the higher-rank digit. As a result, the numerical value displayed in many digits can be read in an extremely easy way.
