    Rational numbers (): Numbers that can be expressed as a ratio of an integer to a non-zero integer. [3] All integers are rational, but there are rational numbers that are not integers, such as −2/9. Real numbers (): Numbers that correspond to points along a line. They can be positive, negative, or zero.

  3. Number - Wikipedia

    en.wikipedia.org/wiki/Number

    The natural numbers form a subset of the integers. As there is no common standard for the inclusion or not of zero in the natural numbers, the natural numbers without zero are commonly referred to as positive integers, and the natural numbers with zero are referred to as non-negative integers.

  4. Real number - Wikipedia

    en.wikipedia.org/wiki/Real_number

    The non-negative real numbers can be noted but one often sees this set noted + {}. [25] In French mathematics, the positive real numbers and negative real numbers commonly include zero, and these sets are noted respectively + and . [26] In this understanding, the respective sets without zero are called strictly positive real numbers and ...

  5. Continuous or discrete variable - Wikipedia

    en.wikipedia.org/wiki/Continuous_or_discrete...

    The value of a discrete variable can be obtained by counting, and the number of permitted values is either finite or countably infinite. Common examples are variables that must be integers, non-negative integers, positive integers, or only the integers 0 and 1. [9]

  6. Natural number - Wikipedia

    en.wikipedia.org/wiki/Natural_number

    Natural numbers are also used as labels, like jersey numbers on a sports team, where they serve as nominal numbers and do not have mathematical properties. [5] The natural numbers form a set, commonly symbolized as a bold N or blackboard bold ⁠ ⁠. Many other number sets are built from the natural numbers. For example, the integers are made ...

    The integers arranged on a number line. An integer is the number zero , a positive natural number (1, 2, 3, . . .), or the negation of a positive natural number (−1, −2, −3, . . .). [1] The negations or additive inverses of the positive natural numbers are referred to as negative integers. [2]

  8. Signedness - Wikipedia

    en.wikipedia.org/wiki/Signedness

    In computing, signedness is a property of data types representing numbers in computer programs. A numeric variable is signed if it can represent both positive and negative numbers, and unsigned if it can only represent non-negative numbers (zero or positive numbers).

  9. Integer (computer science) - Wikipedia

    en.wikipedia.org/wiki/Integer_(computer_science)

    Integral types may be unsigned (capable of representing only non-negative integers) or signed (capable of representing negative integers as well). [1] An integer value is typically specified in the source code of a program as a sequence of digits optionally prefixed with + or −. Some programming languages allow other notations, such as ...
