An '''irrational number''' is a #REDIRECT [[real number]] that cannot be expressed as the ratio of two [[integers]].  Irrational numbers often arise as solutions to problems involving rational numbers. For example, the square root of 2 is irrational. Other irrationals, such as [[pi]], serve as fundamental constants in many mathematical problems. Irrational numbers can never be expressed exactly using decimal notation with a finite number of digits. Instead it is common to write them using only enough significant digits to solve the problem at hand, followed by an ellipsis (…): :$\pi\ = 3.1415926...$ ==See also== [[Transcendental numbers]] [[Category:mathematicsASSFLY JUST LOOVVVVVVVEEEEEEEEESSSSSSSS Z'S MASSIVE COCK]]
