@kou I have a question regarding `arrow::{Sparse,}Tensor` :
Should I consider the following codes for` arrow::Tensor `and
`arrow::SparseTensor` a bug, as `arrow::EqualOptions::atol_ `is not included in
the comparison?
https://github.com/apache/arrow/blob/494d0e389cd96bbf860a31a1ccd6afbefadefb2e/cpp/src/arrow/compare.cc#L1280-L1281

I mean such an assertion, it has passed
```c++
TEST(Tensor,FloatComparasion) {
std::vector<double> v1 = {0.5};
std::vector<double> v2 = {0.5001};
std::shared_ptr<Buffer> b1 = Buffer::Wrap(v1);
std::shared_ptr<Buffer> b2 = Buffer::Wrap(v2);
NumericTensor<DoubleType> t1(b1, {1, 1});
NumericTensor<DoubleType> t2(b2, {1, 1});
auto st1 = SparseCSCMatrix::Make(t1).ValueOrDie();
auto st2 = SparseCSCMatrix::Make(t2).ValueOrDie();
ASSERT_FALSE(t1.Equals(t2, EqualOptions::Defaults().atol(1e-3)));
ASSERT_FALSE(st1->Equals(*st2, EqualOptions::Defaults().atol(1e-3)));
}
```
