Thanks Gero,
Good catch. This does seem like a bug.I am on the go, but later today, I'll add thisas an issue in Git and kick off the discussionfor the fix with the colleagues.
Kind regards, Chris

Current implementation:
inline complex pow(const BOOST_CSTDFLOAT_EXTENDED_COMPLEX_FLOAT_TYPE& x,
const complex& a)
{
return std::exp(a * std::log(x));
}
I think that's correct:
inline complex pow(const BOOST_CSTDFLOAT_EXTENDED_COMPLEX_FLOAT_TYPE& x,
const complex& a)
{
return std::exp(a * std::log(complex(x)));
}
