    The word zero came into the English language via French zéro from the Italian zero, a contraction of the Venetian zevero form of Italian zefiro via ṣafira or ṣifr. [1] In pre-Islamic time the word ṣifr (Arabic صفر) had the meaning "empty". [2] Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: शून्य ...

    The number 0 is represented by zero while null is a representation of an empty set {}. Hence in computer science a zero represents the outcome of a mathematical computation such as 2−2, while null is used for an undefined state (for example, a memory location that has not been explicitly initialised).

    The character 零 (pinyin: líng) means "zero" in Chinese, although 〇 is also common. Etymologically 零 is an onomatopoeic word for "light rain".

  5. Zero of a function - Wikipedia

    en.wikipedia.org/wiki/Zero_of_a_function

    In various areas of mathematics, the zero set of a function is the set of all its zeros. More precisely, if f : X → R {\displaystyle f:X\to \mathbb {R} } is a real-valued function (or, more generally, a function taking values in some additive group ), its zero set is f − 1 ( 0 ) {\displaystyle f^{-1}(0)} , the inverse image of { 0 ...

  6. Zeros and poles - Wikipedia

    en.wikipedia.org/wiki/Zeros_and_poles

    Because of the order of zeros and poles being defined as a non-negative number n and the symmetry between them, it is often useful to consider a pole of order n as a zero of order –n and a zero of order n as a pole of order –n. In this case a point that is neither a pole nor a zero is viewed as a pole (or zero) of order 0.

  9. Zero element - Wikipedia

    en.wikipedia.org/wiki/Zero_element

    A zero morphism in a category is a generalised absorbing element under function composition: any morphism composed with a zero morphism gives a zero morphism. Specifically, if 0 XY : X → Y is the zero morphism among morphisms from X to Y , and f : A → X and g : Y → B are arbitrary morphisms, then g ∘ 0 XY = 0 XB and 0 XY ∘ f = 0 AY .
