Doc No: N3060 Date: 2010-03-06
|
|
Extensions to the C++ Library to support mathematical special functions
|
|
</para>
|
|
|
|
<para>
|
|
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>__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).
|
|
</para>
|
|
|
|
<para>
|
|
When the special functions are declared the macro
|
|
<code>__STDCPP_MATH_SPEC_FUNCS__</code> is defined to <code>201003L</code>.
|
|
</para>
|
|
|
|
<para>
|
|
In addition to the special functions defined in IS 29124, for
|
|
non-strict modes (i.e. <code>-std=gnu++NN</code> modes) the
|
|
hypergeometric functions and confluent hypergeometric functions
|
|
from TR1 are also provided, defined in namespace
|
|
<code>__gnu_cxx</code>.
