11235	Variance error when used with std::complex	Martín Sanz Sabater <martin.sanz@…>	Eric Niebler	"The result of variance in complex numbers sequence must be real, but it is complex.

It is solved changing the line (in ""variance.hpp""):
        this->variance =
                    numeric::fdiv(this->variance * (cnt - 1), cnt)
                  + numeric::fdiv(tmp * tmp, cnt - 1);

with this one:
        this->variance =
                    numeric::fdiv(this->variance * (cnt - 1), cnt)
                  + numeric::fdiv(std::pow(std::abs(tmp),2), cnt - 1);


P.D: sorry, I don't know how to fix it in ""lazy_variance"""	Bugs	new	To Be Determined	accumulator	Boost 1.58.0	Problem
