    *abs_tol* is the absolute tolerance; it defaults to ``0.0`` and it must be
    nonnegative.  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
