Numpy : min/max of integer types

Here is how to find the MIN or MAX values for the Integer types in numpy :

In [235]: np.iinfo(np.int8)                                                                                                                                                  
Out[235]: iinfo(min=-128, max=127, dtype=int8)

In [236]: np.iinfo(np.int16)                                                                                                                                                 
Out[236]: iinfo(min=-32768, max=32767, dtype=int16)

In [237]: np.iinfo(np.int32)                                                                                                                                                 
Out[237]: iinfo(min=-2147483648, max=2147483647, dtype=int32)

In [238]: np.iinfo(np.int64)                                                                                                                                                 
Out[238]: iinfo(min=-9223372036854775808, max=9223372036854775807, dtype=int64)

In [239]: np.iinfo(np.int)                                                                                                                                                   
Out[239]: iinfo(min=-9223372036854775808, max=9223372036854775807, dtype=int64)
