Maximum allowed value for a numpy data type
Solution 1:
min_value = np.iinfo(im.dtype).min
max_value = np.iinfo(im.dtype).max
docs:
-
np.iinfo(machine limits for integer types) -
np.finfo(machine limits for floating point types)
Solution 2:
You're looking for numpy.iinfo for integer types. Documentation here.
There's also numpy.finfo for floating point types. Documentation here.
