There is a library default, for all interval containers of the <span class="bold"><strong>icl</strong></span>. The intension of the library default
is to minimize the need for parameter specification, when working
with <span class="bold"><strong>icl</strong></span> class templates. We can
get the library default interval type as <code class="computeroutput"><span class="identifier">interval</span><span class="special">&lt;</span><span class="identifier">P</span><span class="special">&gt;::</span><span class="identifier">type</span></code>.
The library default uses <span class="emphasis"><em><span class="bold"><strong>dynamically
bounded intervals</strong></span></em></span>. You can switch to <span class="emphasis"><em><span class="bold"><strong>statically bounded intervals</strong></span></em></span> by
<code class="computeroutput"><span class="preprocessor">#define</span> <span class="identifier">BOOST_ICL_USE_STATIC_BOUNDED_INTERVALS</span></code>
prior to icl includes.

For template struct <code class="computeroutput"><span class="identifier">interval</span></code>
that always uses the library default the static functions for the
four interval bound types are also available.

This works with the statically bounded intervals as well, with the
restriction that for continuous domain types the matching function
has to be used:
