docs: Return ``True`` if ``other`` is equal to this set up to ``atol``.
  
          Parameters
          ----------
          other :
              Object to be tested.
          atol : float
              Maximum allowed difference in maximum norm between the
              interval endpoints.
  
          Examples
          --------
          >>> rbox1 = IntervalProd(0, 0.5)
          >>> rbox2 = IntervalProd(0, np.sqrt(0.5)**2)
          >>> rbox1.approx_equals(rbox2, atol=0)  # Numerical error
          False
          >>> rbox1.approx_equals(rbox2, atol=1e-15)
          True
