Thank you for the explanations!

for 2.7.6 type(2 << 62) is <type 'long'> and type(2 << 61) is
<type 'int'> (I suppose it's analogous in a 32 bit machine
around type(2 << 30) so I just wanted to test on that limits).

Is that still relevant? or is too much detail and we should stop here.

Regards,
francis
