Abstract

PURPOSE: To avoid erasure of significant figures under a decimal point by detecting the decimal position of mantissa data in every operation of a specified key and, when the value exceeds the limit of display contents of the mantissa data display portion, inhibiting conversion of display data.
CONSTITUTION: In the miniature electronic computer where display portion 24 for mantissa and exponential data is set and operation of data including the exponential data is executed in arithmetic circuit 16, conversion key 25a, which converts the display data to exponential type, and inversion key 25b are set on key input portion 25. The register region which stores the decimal point position data of the lowest digit of mantissa data display portion, decimal point position data, whose position is higher than the highest position of the display portion by the number of digits corresponding to the number of digits of the display portion and decimal point position data is set in RAM3. A stated number is added to the exponential data or reduced from it in every operation of key 25a or 25b and the same manner is applied to the decimal point position data; when the value exceeds the limit of display contents mantissa data display portion, conversion of the display data is inhibited by the output of timing decorder 9.
