The names for the number 0 include "zero", "cipher", "null", "naught", "nought", "love", "duck", "nil", "nada", "zilch", "zip", "o", "aught", and "ought". There are various subtleties of usage amongst them all.
Ok right. 0 has a lot of name. I am looking for a word to name a number or a group of number who can be any digits but strictly not equals to 0. Positive, negative, complex, whatever but 0. When I search about opposite of 0, I found about -0 but it is still 0.
Is there a name for all numbers different than zero?
Answer
In programming, we would write this as not 0 or !0. If we search about not 0 number or non 0 number we find an answer.
A quantity which does not equal zero is said to be nonzero. A real nonzero number must be either positive or negative, and a complex nonzero number can have either real or imaginary part nonzero.
A nonzero number is any number that is not equal to zero. This includes both positive and negative numbers as well as fractions and irrational numbers.
Chemists, mathematicians and scientists who complete equations in their research consider all nonzero numbers to have meaning or significance whether the number is negative or positive. Any number, whether positive or negative, that does not equate to zero essentially represents a nonzero number.
Also on math.stackexchange.com:
An integer is any whole number or its negative, e.g. ..., -2, -1, 0, 1, 2, ...
A non-zero integer is any of these but 0.
What does non-zero integer mean?
