Just another name for (double) Pi. It is actually defined in almost all C and C++ math libraries, but the ISO standard language bindings disable that definition, perhaps because it is officially supposed to be implemented as a global double constant rather than just a symbolic value. You can put switches on most compilers that will make the library definition visible, but just defining it (conditionally) yourself is easier and more portable.
