Thanks a lot for your work. Easy to use and efficient !
I just had to fix the log10 and log2 function in dval.h
At least on my computer (Apple with clang, the constexpr k does not compile, I think because std::log has not been "constexprefied" by Apple :-( )

const auto OneOnlog10=1.0 / std::log(10.0);
template <uint32_t N>
inline DVal log10(const DVal& x)
{
DVal dval(x, false);
dval.d[0] = std::log10(x.d[0]);
double k = OneOnlog10;//1.0 / std::log(10.0);
const double c = k / x.d[0];
const uint32_t nn = x.n();
for (uint32_t i = 1; i < nn; ++i)
dval.d[i] = x.d[i] * c;
return dval;
}
const auto OneOnlog2=1.0 / std::log(2.0);
template <uint32_t N>
inline DVal log2(const DVal& x)
{
DVal dval(x, false);
dval.d[0] = std::log2(x.d[0]);
double k = OneOnlog2;//1.0 / std::log(2.0);
const double c = k / x.d[0];
const uint32_t nn = x.n();
for (uint32_t i = 1; i < nn; ++i)
dval.d[i] = x.d[i] * c;
return dval;
}
