<a name="id-1.3.35.5.6.42.4.4"></a><h2>Description</h2>
<p>This trait has a single member <code class="computeroutput">type</code> which is either the unsigned type corresponding to T or an unbounded integer type. This trait is used to generate types suitable for the calculation of a range: as a result if T is signed, then member <code class="computeroutput">type</code> <span class="emphasis"><em>should define a type with one more bit precision than T</em></span>. For built-in types this trait defaults to <code class="computeroutput">boost::make_unsigned&lt;T&gt;::type</code>. For user defined types it simply asserts that the argument type T is either an unbounded integer, or an unsigned one (using std::numeric_limits). User defined specializations may be provided for other cases. </p>
