  1. zeroth

    "Zeroth" typically refers to something that comes before the "first" in a series, process or system.

The term "zeroth" is not often used in everyday language, more commonly seen in a scientific, mathematical, or technical context.

The New Hacker's Dictionary

  1. zeroth

    First. Among software designers, comes from C's and LISP's 0-based indexing of arrays. Hardware people also tend to start counting at 0 instead of 1; this is natural since, e.g., the 256 states of 8 bits correspond to the binary numbers 0, 1, ..., 255 and the digital devices known as counters count in this way.Hackers and computer scientists often like to call the first chapter of a publication ‘Chapter 0’, especially if it is of an introductory nature (one of the classic instances was in the First Edition of K&R). In recent years this trait has also been observed among many pure mathematicians (who have an independent tradition of numbering from 0). Zero-based numbering tends to reduce fencepost errors, though it cannot eliminate them entirely.
