+ Many of the special functions included in this library are also a part
+ of the either the <a href="http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1256.pdf" target="_top">C99
+ Standard ISO/IEC 9899:1999</a> or the <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1836.pdf" target="_top">Technical
+ Report on C++ Library Extensions</a>. Therefore this library includes
+ a thin wrapper header <code class="computeroutput">boost/math/tr1.hpp</code>
+ that provides compatibility with these two standards.
+ 
+
+ 
+
+ There are various pros and cons to using the library in this way:
+ 
+
+ 
+
+ Pros:
+ 
+
+ 
+<div class="itemizedlist"><ul type="disc">
+<li>
+ The header to include is lightweight (i.e. fast to compile).
+ </li>
+<li>
+ The functions have extern "C" linkage, and so are usable from
+ other languages (not just C and C++).
+ </li>
+<li>
+ C99 and C++ TR1 Standard compatibility.
+ </li>
+</ul></div>
+
+ 
+
+ Cons:
+ 
+
+ 
+<div class="itemizedlist"><ul type="disc">
+<li>
+ You will need to compile and link to the external Boost.Math libraries.
+ </li>
+<li>
+ Limited to support for the types, <code class="computeroutput">float</code>,
+ <code class="computeroutput">double</code> and <code class="computeroutput">long double</code>.
+ </li>
+<li>
+ Error handling is handled via setting ::errno and returning NaN's and
+ infinities: this may be less flexible than an C++ exception based approach.
+ </li>

+
+ This library now presents the user with a choice:
+ 
+
+ 
+<div class="itemizedlist"><ul type="disc">
+<li>
+ To include the header only versions of the functions and have an easier
+ time linking, but a longer compile time.
+ </li>
+<li>
+ To include the TR1 headers and link against an external library.
+ </li>
+</ul></div>
+
+ 
+
+ Which option you choose depends largely on how you prefer to work and how
+ your system is set up.
+ 
+
+ 
+
+ For example a casual user who just needs the acosh function, would probably
+ be better off including <code class="computeroutput"><boost/math/special_functions/acosh.hpp></code>
+ and using <code class="computeroutput">boost::math::acosh(x)</code> in
+ their code.
+ 
+
+ 
+
+ 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"><boost/math/tr1.hpp></code> and using <code class="computeroutput">boost::math::tr1::acosh(x)</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="../perf/getting_best.html" title="Getting the Best Performance from this Library">release and debug builds
+ can be as much as 20 times</a>, so for complex applications this can
+ be a big win.

+ These functions provide the same functionality as the macros with the same
+ name in C99, indeed if the C99 macros are available, then these functions
+ are implemented in terms of them, otherwise they rely on std::numeric_limits<>
+ to function.
+ 
+
+ Note that the definition of these functions does not suppress the
+ definition of these names as macros by math.h on those platforms
+ that already provide these as macros. That mean that the following have differing
+ meanings:
+ 
+<pre class="programlisting">using namespace boost::math;
+
+// This might call a global macro if defined,
+// but might not work if the type of z is unsupported
+// by the std lib macro:
+isnan(z);
+//
+// This calls the Boost version
+// (found via the "using namespace boost::math" declaration)
+// it works for any type that has numeric_limits support for type z:
+(isnan)(z);
+//
+// As above but with namespace qualification.
+(boost::math::isnan)(z);
+//
+// This will cause a compiler error if isnan is a native macro:
+boost::math::isnan(z);
+// So always use instead:
+(boost::math::isnan)(z);
+//
+// You can also add a using statment,
+// globally to a .cpp file, or to a local function in a .hpp file.
+using boost::math::isnan;
+// so you can write the shorter and less cluttered
+(isnan)(z)
+// But, as above, if isnan is a native macro, this causes a compiler error,
+// because the macro always 'gets' the name first, unless enclosed in () brackets.
+</pre>
+
+ Detailed descriptions for each of these functions follows:
+ 
+<pre class="programlisting">template <class T>
+int fpclassify(T t);
