1. A prioritizing numeric data input apparatus that outputs numeric data selected by a user, comprising:

  • an input device having a group of different numeric digits associated therewith, said numeric digits being represented by indicia that are located on said input device in close proximity to each other and being selectable by a user via said input device, with said input device being responsive to the selection of one or more of said numeric digits to provide at least one input signal indicative of said selected numeric digits;

    an electronic circuit coupled to said input device to receive said one or more input signals, said circuit being operable in response to a single one of said numeric digits being selected to provide an output signal indicative of that single selected numeric digit;

    said circuit further being operable in response to a plurality of said numeric digits being simultaneously selected by the user to provide an output signal indicative of the numeric value of the largest of the numeric digits simultaneously selected by the user, whereby numerically larger digits are given priority over numerically smaller digits.
