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:

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.

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)
