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. |
>>> 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)
