When comparing ``x`` to ``0.0``, ``isclose(x, 0)`` is computed - as ``abs(x) <= rel_tol * abs(x)``, which is ``False`` for any ``x`` and - rel_tol less than ``1.0``. So add an appropriate positive abs_tol argument + as ``abs(x) <= rel_tol * abs(x)``, which is ``False`` for any nonzero ``x`` and + *rel_tol* less than ``1.0``.
