Hi,
For this formula,

(declare-fun a () (_ BitVec 1))
(declare-fun b () (_ BitVec 40))
(declare-fun c () (_ BitVec 6))
(assert (= 0 (fp.to_real (fp a b c))))

I would have a question regarding strategies for quantifier instantiations.
For the attached file, CVC4 version 1.7 returns unknown when no options are used. I believe this result is expected, as wi…
