params=(('zero_accuracy', UINT, 0, 'one of the most time-consuming operations in the real algebraic number module is determining the sign of a polynomial evaluated at a sample point with non-rational algebraic number values. Let k be the value of this option. If k is 0, Z3 uses precise computation. Otherwise, the result of a polynomial evaluation is considered to be 0 if Z3 can show it is inside the interval (-1/2^k, 1/2^k)'),
('min_mag', UINT, 16, 'Z3 represents algebraic numbers using a (square-free) polynomial p and an isolating interval (which contains one and only one root of p). This interval may be refined during the computations. This parameter specifies whether to cache the value of a refined interval or not. It says the minimal size of an interval for caching purposes is 1/2^16'),
