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)
