Checking type of big integer values without sign
<p>There is this code:</p>

<pre><code>print isinstance(2147483647, int) # True - max signed 32-bit integer
print isinstance(4294967295, int) # False - max unsigned 32-bit integer
print isinstance(18446744073709551615, int) # False - max unsigned 64-bit integer
</code></pre>

<p>How to check if value is unsigned 32-bit integer and unsigned 64-bit integer?</p>
