[Numpy-discussion] Possible

[Michal Radwanski]

Hello,

I'm not sure if it's expected behaviour or a bug, so I decided to write
here. First an example:
In [4]: array([2**63]) 
Out[4]: array([9223372036854775808], dtype=uint64)

In [5]: array([2**63-1, 2**63]) 
Out[5]: array([9.22337204e+18, 9.22337204e+18])


The docs for `numpy.array` mention, that:

dtype : data-type, optional
 The desired data-type for the array. If not given, then the type 
 will be determined as the minimum type required to hold 
 the objects in the sequence.

I understand the type promotions here, but I believe that the
documentation is wrong in this case. Indeed, the minumum type in the
latter case would be 'uint64'.

Is it a bug worth submitting/fixing?
