Features:

• Exact real and complex numbers represented as elements of automatically extended multivariate fields
• Support for algebraic, transcendental and mixed fields
• Automatic, rigorous numerical embeddings and arbitrary-precision numerical evaluation (on top of Arb)
• 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)
• Multivariate rational functions (on top of Flint)
• Gröbner basis computation (on top of Flint)
• Symbolic expressions (conversions, evaluation, LaTeX output)
