Nikolaj Bjorner a6fcdecfd7 Add accessor for lower/upper bounds of algebraic numerals #3245 ... The pretty printer for algebraic numerals prints a polynomial root expression, however, polynomial root expressions are not exposed over the API. The C API contains methods for approximating root objects from above and below with arbitrary precision. These functions are now exposed over the C++ API. Note that algebraic numbers are also disjoint from rcf (real closed field) objects. Thus, z3 doesn't support adding "pi" as an extension field to algebraic numbers that are used by the nlsat solver. It operats on algebraic numbers formed by roots over polynomial with rational coefficients		2020-03-12 14:23:45 -07:00
