Algebraic Numbers

The Wolfram Language'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, the Wolfram Language efficiently handles Root objects just as it does ordinary explicit representations of numbers.
