Summary
Add behavioral coverage for Z3 issue 10175 across the denormal leading-zero count
boundary and both the narrow and widened exponent paths. The regressions cover exact
division; upper and lower exponent endpoints for exponent widths 2, 3, and 4; two-bit
workspace growth in FP(2,16); the reported negative overflow under
RTZ; the originalreal-to-FP conversion and model-validation path; and the opposite
RTNresult.Issue: Z3Prover/z3#10175.
Source change: Z3Prover/z3#10216.
Testing
No local tests were run; validation is delegated to the paired fork CI workflow.
