 Algebraic Numbers Mathematica's symbolic character allows it to provide deep integrated support for algebraic numbers. At the core are Root objects, which provide exact implicit representations for arbitrary algebraic numbers. Using specially developed algorithms, Mathematica efficiently handles Root objects just as it does ordinary explicit representations of numbers. Root — symbolic representation for the root of a polynomial N — numerical approximation to any precision      MinimalPolynomial — the minimal polynomial for which a number is a root IsolatingInterval — exact isolating interval for an algebraic number      RootReduce — attempt to reduce to a single Root object ToRadicals — convert to explicit radicals, if possible      Algebraics — the domain of algebraic numbers, for FullSimplify etc.      RootApproximant — find an algebraic number that approximates a given number ContinuedFraction — non-periodic and periodic continued fractions AlgebraicNumber — algebraic number represented in a particular field ToNumberField — express numbers in a particular algebraic number field TUTORIALS Algebraic Numbers Algebraic Number Fields Real Polynomial Systems Counting and Isolating Polynomial Roots TUTORIAL COLLECTION Advanced Algebra MORE ABOUT Number Theory Continued Fractions Number Recognition Polynomial Algebra
