std::pow(float, int) actually gets promoted to std::pow(double, double).
Note that this is correct as of c++11: http://en.cppreference.com/w/cpp/numeric/math/pow
This is especially bad for std::pow(x, 2). Inside Eigen we can use
Does pow(x, 2.0) fix it? If not, pow(x, float(2)) at least should... Ilja
