- Efficient field arithmetic (on top of Flint and Antic)
- Automatic, rigorous simplification (using integer relations, ideal reduction, and other methods)
- Complete decision procedures for algebraic numbers
- Partial decision procedures for transcendental numbers
- Polynomials and matrices with exact coefficients
- Exact real and complex algebraic numbers (absolute minpoly representation)
