   4     The header <code class="filename">limits</code> defines
   5     traits classes to give access to various implementation
   6     defined-aspects of the fundamental types. The traits classes --
   7     fourteen in total -- are all specializations of the template class
   8     <code class="classname">numeric_limits</code>, documented <a class="ulink" href="http://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/structstd_1_1numeric__limits.html" target="_top">here</a>
