--- Comment #13 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- MPFR deals with larger exponent ranges for intermediate computations itself (MPFR functions generally set the maximum possible exponent range internally). MPC generally doesn't seem to, so quite likely setting an exponent range could show up some MPC bugs.
