@wintersteiger
This example exposes a bug in is_unique_value
```
(assert (= (fp.to_real ((_ to_fp 8 24) (_ bv4286579200 32))) (fp.to_real ((_ to_fp 8 24) (_ bv4286578944 32)))))
(check-sat)
```
It returns true for fp representations that map to NaN. It can only return true for fp values that are unique relative to having no other bit-vector representation so not corresponding to an equivalence class of values such as NaN.
I am having it return false. If there is a way to refine the test it will catch some earlier inferences.
