Maximum allowed value for a numpy data type

Question

I am working with numpy arrays of a range of data types (uint8, uint16, int16, etc.). I would like to be able to check whether a number can be represented within the limits

Answer 1

You're looking for numpy.iinfo for integer types. Documentation here.

There's also numpy.finfo for floating point types. Documentation here.

Answer 2

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)
