ABSTRACT:
A data processing system for use in a measuring instrument having a keyboard with a plurality of numeric keys for entering numeric values and a plurality of terminator keys for indicating the completion of the entering of numeric values. Each of the terminator keys has associated therewith a pair of reciprocal exponents to indicate the weight to be applied to the numeric value. A processor is coupled to the terminator keys for automatically selecting one of the reciprocal exponents. That selection is deduced by the processor from the nature of the calculation.
