We do so here, for the C++ library only. Behavior of the

compiler, linker, runtime loader, and other elements of "the

in Annex B, Implementation Qualities, are also part of the

compiler, not the library.

This table is based on the table of contents of ISO/IEC FDIS 29124
|

Doc No: N3060 Date: 2010-03-06
|
||
Extensions to the C++ Library to support mathematical special functions
|
||
</p><p>
|
||
Complete support for IS 29124 is in GCC 6.1 and later releases, when using
|
||
at least C++11 (for older releases or C++98/C++03 use TR1 instead).
|
||
For C++11 and C++14 the additions to the library are not declared by their
|
||
respective headers unless <code class="code">__STDCPP_WANT_MATH_SPEC_FUNCS__</code>
|
||
is defined as a macro that expands to a non-zero integer constant.
|
||
For C++17 the special functions are always declared (since GCC 7.1).
|
||
</p><p>
|
||
When the special functions are declared the macro
|
||
<code class="code">__STDCPP_MATH_SPEC_FUNCS__</code> is defined to <code class="code">201003L</code>.
|
||
</p><p>
|
||
In addition to the special functions defined in IS 29124, for
|
||
non-strict modes (i.e. <code class="code">-std=gnu++NN</code> modes) the
|
||
hypergeometric functions and confluent hypergeometric functions
|
||
from TR1 are also provided, defined in namespace
|
||
<code class="code">__gnu_cxx</code>.
