API: Enforce float64 precision for `assert_almost_equal`
This ensures that the precision is not downcast, which could make
a small value zero (for float16 mostly).
This lets tests pass that check whether `np.float16(0)` is almost
equal to 0, which otherwise fail (because `float16(0.00000001)`
will evaluate to 0 exactly.
