digit From Latin digitus, translating as finger or toe. Any of the Arabic numerals 1–9, and usually 0, used to represent numbers in the decimal system, and so-called because they originally were counted on the fingers. Note: Romans counted with letters, rather than numbers, partially because they hadn’t invented 0 (zero). The theory is that the Roman system derived from the Etruscan system for counting sheep by making notches on tally sticks. I don’t know what the Romans were doing with their fingers during this period in history. See also decimal notation. |
