Zero : \Ze"ro\, n.; pl. Zerosor Zeroes. [F. z['e]ro, from Ar.
[,c]afrun, [,c]ifrun, empty, a cipher. Cf. Cipher.]
1. (Arith.) A cipher; nothing; naught.
2. The point from which the graduation of a scale, as of a
thermometer, commences.
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.
3. Fig.: The lowest point; the point of exhaustion; as, his
patience had nearly reached zero.
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.

Zero :
1. 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
Burroughs/{Unisys">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".
