How to get "finfo" in C++ torchlib like that in pytorch

I am using C++ torchlib, but I don’t know what to do it in c++ like that in pytorch:

        min_real = torch.finfo(self.logits.dtype).min
# or
        min_real = torch.finfo(self.logits.dtype).tiny

I don’t think finfo is exposed in libtorch, but you should be able to use e.g.:

const auto int_min = std::numeric_limits<int>::min();
const auto int_max = std::numeric_limits<int>::max();
