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<T>::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> 41</div> 42</div> 43<table xmlns:rev="http://www.cs.rpi.edu/~gregod/boost/tools/doc/revision" width="100%"><tr> 44<td align="left"></td> 45<td align="right"><div class="copyright-footer">Copyright © 2000-2005 Jens Maurer<br>Copyright © 2009, 2010 Steven Watanabe<p> 46 Distributed under the Boost Software License, Version 1.0.
