This library now presents the user with a choice:

</p>
|

|
|
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
|

|
||
|

|
</li>
|
||
|
|
</ul></div>
|
||
|
|
<p>
|
||
|
|
Which option you choose depends largely on how you prefer to work and how your
|
||
|
|
system is set up.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
For example a casual user who just needs the acosh function, would probably
|
||
|
|
be better off including <code class="computeroutput"><span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">math</span><span class="special">/</span><span class="identifier">special_functions</span><span class="special">/</span><span class="identifier">acosh</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span></code> and using <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">acosh</span><span class="special">(</span><span class="identifier">x</span><span class="special">)</span></code> in their code.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
However, for large scale software development where compile times are significant,
|
||
|
|
and where the Boost libraries are already built and installed on the system,
|
||
|
|
then including <code class="computeroutput"><span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">math</span><span class="special">/</span><span class="identifier">tr1</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span></code> and using <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">math</span><span class="special">::</span><span class="identifier">tr1</span><span class="special">::</span><span class="identifier">acosh</span><span class="special">(</span><span class="identifier">x</span><span class="special">)</span></code>
|
||
|
|
will speed up compile times, reduce object files sizes (since there are no
|
||
|
|
templates being instantiated any more), and also speed up debugging runtimes
|
||
|
|
- since the externally compiled libraries can be compiler optimised, rather
|
||
|
|
than built using full settings - the difference in performance between <a class="link" href="getting_best.html" title="Getting the Best Performance from this Library: Compiler and Compiler Options">release and debug builds can be as much
|
||
|
|
as 20 times</a>, so for complex applications this can be a big win.
