  2. Positive operator - Wikipedia

    en.wikipedia.org/wiki/Positive_operator

    The operator is said to be positive-definite, and written >, if , >, for all ⁡ {}. [ 1 ] Many authors define a positive operator A {\displaystyle A} to be a self-adjoint (or at least symmetric) non-negative operator.

  3. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor. [ 1 ] For example, the expression "5 mod 2" evaluates to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0 ...

  4. Three-way comparison - Wikipedia

    en.wikipedia.org/wiki/Three-way_comparison

    In C++, the C++20 revision adds the spaceship operator <=>, which returns a value that encodes whether the 2 values are equal, less, greater, or unordered and can return different types depending on the strictness of the comparison. [3] The name's origin is due to it reminding Randal L. Schwartz of the spaceship in an HP BASIC Star Trek game. [4]

    modal operator for “it is possible that”, (in most modal logics it is defined as “¬ ¬”, “it is not necessarily not”).

  6. Signed zero - Wikipedia

    en.wikipedia.org/wiki/Signed_zero

    Signed zero is zero with an associated sign.In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are equivalent. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in ...

  7. Positive - Wikipedia

    en.wikipedia.org/wiki/Positive

    Positive operator, a type of linear operator in mathematics; Positive result, a result that has been found significant in statistical hypothesis testing; Positive test, a diagnostic test result that indicates some parameter being evaluated was present; Positive charge, one of the two types of electrical charge; Positive (electrical polarity ...

  8. Conditional operator - Wikipedia

    en.wikipedia.org/wiki/Conditional_operator

    and | are bitwise operators that occur in many programming languages. The major difference is that bitwise operations operate on the individual bits of a binary numeral, whereas conditional operators operate on logical operations. Additionally, expressions before and after a bitwise operator are always evaluated.

  9. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    In computer programming, an operator is a programming language construct that provides functionality that may not be possible to define as a user-defined function (i.e. sizeof in C) or has syntax different than a function (i.e. infix addition as in a+b).
