  2. Irrational number - Wikipedia

    en.wikipedia.org/wiki/Irrational_number

    The number √ 2 is irrational.. In mathematics, the irrational numbers (in-+ rational) are all the real numbers that are not rational numbers.That is, irrational numbers cannot be expressed as the ratio of two integers.

  3. List of representations of e - Wikipedia

    en.wikipedia.org/wiki/List_of_representations_of_e

    Since e is an irrational number (see proof that e is irrational), it cannot be represented as the quotient of two integers, but it can be represented as a continued fraction. Using calculus , e may also be represented as an infinite series , infinite product , or other types of limit of a sequence .

  7. Algebraic number - Wikipedia

    en.wikipedia.org/wiki/Algebraic_number

    It includes all quadratic irrational roots, all rational numbers, and all numbers that can be formed from these using the basic arithmetic operations and the extraction of square roots. (By designating cardinal directions for +1, −1, + i , and − i , complex numbers such as 3 + i 2 {\displaystyle 3+i{\sqrt {2}}} are considered constructible.)

  8. Rational number - Wikipedia

    en.wikipedia.org/wiki/Rational_number

    A real number that is not rational is called irrational. [5] Irrational numbers include the square root of 2 (⁠ ⁠), π, e, and the golden ratio (φ). Since the set of rational numbers is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. [1]

  9. Commensurability (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Commensurability_(mathematics)

    However, the numbers and 2 are incommensurable because their ratio, , is an irrational number. More generally, it is immediate from the definition that if a and b are any two non-zero rational numbers, then a and b are commensurable; it is also immediate that if a is any irrational number and b is any non-zero rational number, then a and b are ...
