Abstract : We present an efficient constraint programming (CP) approach to the SMTLIB theory of quantifier-free floating-point arithmetic (QF FP). We rely on dense interreduction between many domain representations to greatly reduce the search space. We compare our tool to current state-of-the-art SMT solvers and show that it is consistently better on large problems involving non-linear arithmetic operations (for which bit-blasting techniques tend to scale badly). Our results emphasize the importance of the conservation of the high-level structure of the original problems.
