The set of algebraic numbers is composed of all the complex numbers that are roots of nonzero polynomials with rational coefficients. Notable subsets of this set are the integers, the rational numbers and the constructible numbers. Wolfram|Alpha can be used to detect, compute properties of and perform calculations with algebraic numbers.
