def geterr() 

Description

geterr.__doc__

    Get the current way of handling floating-point errors.

    Returns
    -------
    res : dict
        A dictionary with keys "divide", "over", "under", and "invalid",
        whose values are from the strings "ignore", "print", "log", "warn",
        "raise", and "call". The keys represent possible floating-point
        exceptions, and the values define how these exceptions are handled.

    See Also
    --------
    geterrcall, seterr, seterrcall

    Notes
    -----
    For complete documentation of the types of floating-point exceptions and
    treatment options, see `seterr`.

    Examples
    --------
    >>> from collections import OrderedDict
    >>> sorted(np.geterr().items())
    [('divide', 'warn'), ('invalid', 'warn'), ('over', 'warn'), ('under', 'ignore')]
    >>> np.arange(3.) / np.arange(3.)
    array([nan,  1.,  1.])

    >>> oldsettings = np.seterr(all='warn', over='raise')
    >>> OrderedDict(sorted(np.geterr().items()))
    OrderedDict([('divide', 'warn'), ('invalid', 'warn'), ('over', 'raise'), ('under', 'warn')])
    >>> np.arange(3.) / np.arange(3.)
    array([nan,  1.,  1.])
