Algebraic number
From Aware Theory
In mathematics, an algebraic number is a number that is a root of a non-zero polynomial in one variable with rational coefficients (or equivalently—by clearing denominators—with integer coefficients). Numbers such as π that are not algebraic are said to be transcendental. Almost all real and complex numbers are transcendental. (Here "almost all" has the sense "all but a countable set".) http://en.wikipedia.org/wiki/Algebraic_number
