ToNumberField

ToNumberField[a, θ] expresses the algebraic number a in the number field generated by θ.

• ToNumberField[{a1, a2, ...}, θ] expresses the ai in the field generated by θ.
• ToNumberField[{a1, a2, ...}] expresses the ai in a common extension field generated by a single algebraic number.

Examples

ToNumberField[Sqrt[2], Sqrt[2]]

ToNumberField[{Sqrt[2], Sqrt[3]}]
