numpy.ma.default_fill_value¶
-
numpy.ma.default_fill_value(obj)[source]¶ Return the default fill value for the argument object.
The default filling value depends on the datatype of the input array or the type of the input scalar:
datatype default bool True int 999999 float 1.e20 complex 1.e20+0j object ‘?’ string ‘N/A’ Parameters: obj : ndarray, dtype or scalar
The array data-type or scalar for which the default fill value is returned.
Returns: fill_value : scalar
The default fill value.
Examples
>>> np.ma.default_fill_value(1) 999999 >>> np.ma.default_fill_value(np.array([1.1, 2., np.pi])) 1e+20 >>> np.ma.default_fill_value(np.dtype(complex)) (1e+20+0j)
