| <p> |
| The <code class="computeroutput"><span class="identifier">uint_parser</span></code> class |
| is the simplest among the members of the numerics package. The <code class="computeroutput"><span class="identifier">uint_parser</span></code> can parse unsigned integers |
| of arbitrary length and size. The <code class="computeroutput"><span class="identifier">uint_parser</span></code> |
| parser can be used to parse ordinary primitive C/C++ integers or even |
| user defined scalars such as bigints (unlimited precision integers) as |
| long as the type follows certain expression requirements (documented |
| below). The <code class="computeroutput"><span class="identifier">uint_parser</span></code> |
| is a template class. Template parameters fine tune its behavior. |
