Return the minimum value that can be represented by the dtype of an object.

This function is useful for calculating a fill value suitable for taking the maximum of an array with a given dtype.

Parameters :

obj : {ndarray, dtype}

An object that can be queried for it’s numeric type.

Returns :

val : scalar

The minimum representable value.

Raises :

TypeError :

If obj isn’t a suitable numeric type.

Return current fill value.


>>> import as ma
>>> a = np.int8()
>>> ma.maximum_fill_value(a)
>>> a = np.int32()
>>> ma.maximum_fill_value(a)

An array of numeric data can also be passed.

>>> a = np.array([1, 2, 3], dtype=np.int8)
>>> ma.maximum_fill_value(a)
>>> a = np.array([1, 2, 3], dtype=np.float32)
>>> ma.maximum_fill_value(a)
