AlgebraicNumber

AlgebraicNumber[, {c0, c1, ..., cn}]
represents the algebraic number in the field given by .

DetailsDetails

  • AlgebraicNumber objects in the same field are automatically combined by arithmetic operations.
  • The generator can be any algebraic number, represented in terms of radicals or Root objects. The coefficients must be integers or rational numbers.
  • AlgebraicNumber is automatically reduced so that is an algebraic integer, and the list of is of length equal to the degree of the minimal polynomial of .
  • AlgebraicNumber objects are always treated as numeric quantities.
  • N finds the approximate numerical value of an AlgebraicNumber object.
  • Operations such as Abs, Re, Round, and Less can be used on AlgebraicNumber objects.
  • RootReduce can be used to transform AlgebraicNumber objects into Root objects.
  • A particular algebraic number can have many different representations as an AlgebraicNumber object. Each representation is characterized by the generator specified for the field.
  • AlgebraicNumber objects representing integers or rational numbers are automatically reduced to explicit integer or rational form.
