0 (zero; BrE: /ˈzɪərəʊ/ or AmE: /ˈziːroʊ/) is both a number and the
numerical digit used to represent that number in numerals. It fulfills a
central role in
mathematics as the additive identity of the integers, real numbers,
and many other algebraic structures. As a digit, 0 is used as a placeholder
in
place value systems. Names for the number 0 in English include zero,
nought or (US) naught (/ˈnɔːt/), nil, or — in contexts where at least one
adjacent digit distinguishes it from the letter "O" — oh or o
(/ˈoʊ/). Informal or slang terms for zero include zilch and zip. Ought and
aught (/ˈɔːt/),
as well as cipher, have also been used historically.
I like this, but was expecting information about the `mean` function... :)
I tried a few other words, but couldn't get their definitions. Disappointed
not to find `zilch`:
Couldn't find zilch
Perhaps you meant zip
True enough.
Or perhaps this is just a nice Easter egg, rather than an interesting
glitch in the software matrix...
