<p>A digital data processing system for protecting and controlling an electric system, wherein plural data values indicative of system limits are generated and supplied to a processing unit for processing thereof. The data values are converted to digital signals and stored in a digital memory at addresses selected by an address designation unit. Each memory address has associated therewith a predetermined decimal point position. Addresses from the address designation unit are converted to decimal point display signals which can be stored in the memory and used by the processing unit to determine the decimal point position during processing of the data signals stored in the memory.</p> |
