[ F. z[' e] ro, from Ar. [, c] afrun, [, c] ifrun, empty, a cipher. Cf. { Cipher}.] [ 1913 Webster] 1. ( Arith.) A cipher; nothing; naught. [ 1913 Webster] 2. The point from which the graduation of a scale, as of a thermometer, commences. [ 1913 Webster] Note: Zero in the Centigrade, or Celsius thermometer, and in the R[' e] aumur thermometer, is at the point at which water congeals. The zero of the Fahrenheit thermometer is fixed at the point at which the mercury stands when immersed in a mixture of snow and common salt. In Wedgwood' s pyrometer, the zero corresponds with 1077[ deg] on the Fahrenheit scale. See Illust. of { Thermometer}. [ 1913 Webster] 3. Fig.: The lowest point; the point of exhaustion; as, his patience had nearly reached zero. [ 1913 Webster] { Absolute zero}. See under { Absolute}. { Zero method} ( Physics), a method of comparing, or measuring, forces, electric currents, etc., by so opposing them that the pointer of an indicating apparatus, or the needle of a galvanometer, remains at, or is brought to, zero, as contrasted with methods in which the deflection is observed directly; -- called also { null method}. { Zero point}, the point indicating zero, or the commencement of a scale or reckoning. [ 1913 Webster] [ 1913 Webster] 52 Moby Thesaurus words for " zero": absolute zero, aught, blank, boiling point, cipher, concentrate on, dew point, duck, dud, dummy, fix on, focus on, freezing point, goose egg, hollow man, home in on, insignificancy, jackstraw, lay figure, man of straw, melting point, nada, nadir, naught, nebbish, nichts, nihil, nil, nix, no such thing, nobody, nonentity, nothing, nothing at all, nothing on earth, nothing whatever, nought, null, nullity, pinpoint, puppet, pushover, recalescence point, rock bottom, temperature, thing of naught, trifle, void, whiffet, whippersnapper, zero in on, zilch1. 0, {ASCI} character 48. Numeric zero, as
opposed to the letter "O" (the 15th letter of the English
alphabet). In their unmodified forms they look a lot alike,
and various {kluges} invented to make them visually distinct
have compounded the confusion.
If your zero is centre-dotted and letter-O is not, or if
letter-O looks almost rectangular but zero looks more like an
American football stood on end (or the reverse), you're
probably looking at a modern character display (though the
dotted zero seems to have originated as an option on {IBM
3270} controllers). If your zero is slashed but letter-O is
not, you're probably looking at an old-style {ASCII} graphic
set descended from the default typewheel on the venerable
{ASR-33} {Teletype} (Scandinavians, for whom slashed-O is a
letter, curse this arrangement).
If letter-O has a slash across it and the zero does not, your
display is tuned for a very old convention used at {IBM} and a
few other early mainframe makers (Scandinavians curse *this*
arrangement even more, because it means two of their letters
collide). Some {Burroughs}/{Unisys} equipment displays a zero
with a *reversed* slash. And yet another convention common on
early {line printers} left zero unornamented but added a tail
or hook to the letter-O so that it resembled an inverted Q or
cursive capital letter-O.

2. To set to zero. Usually said of small pieces of data, such
as bits or words (especially in the construction "zero out").
3. To erase; to discard all data from. Said of disks and
directories, where "zeroing" need not involve actually writing
zeroes throughout the area being zeroed. One may speak of
something being "logically zeroed" rather than being
"physically zeroed".
See {scribble}.
