13 This table is based on the table of contents of ISO/IEC FDIS 29124,
14 Doc No: N3060, Date: 2010-03-06,
15 "Extensions to the C++ Library to support mathematical special functions".
16 </para>
18 <para>
19 Complete support for IS 29124 is in GCC 6.1 and later releases, when using
20 at least C++11 (for older releases or C++98/C++03 use TR1 instead).
21 For C++11 and C++14 the additions to the library are not declared by their
22 respective headers unless <code>__STDCPP_WANT_MATH_SPEC_FUNCS__</code>
23 is defined as a macro that expands to a non-zero integer constant.
24 For C++17 the special functions are always declared (since GCC 7.1).
25 </para>
27 <para>
28 When the special functions are declared the macro
29 <code>__STDCPP_MATH_SPEC_FUNCS__</code> is defined to <code>201003L</code>.
30 </para>
32 <para>
33 In addition to the special functions defined in IS 29124, for
34 non-strict modes (i.e. <code>-std=gnu++NN</code> modes) the
35 hypergeometric functions and confluent hypergeometric functions
36 from TR1 are also provided, defined in namespace
37 <code>__gnu_cxx</code>.
