| * __tg_impl_simple(x, y, z, fn, fnf, fnl, ...) |
| * Invokes fnl() if the corresponding real type of x, y or z is long |
| * double, fn() if it is double or any has an integer type, and fnf() |
| * otherwise. |
| * __tg_impl_full(x, y, z, fn, fnf, fnl, cfn, cfnf, cfnl, ...) |
| * Invokes [c]fnl() if the corresponding real type of x, y or z is long |
| * double, [c]fn() if it is double or any has an integer type, and |
| * [c]fnf() otherwise. The function with the 'c' prefix is called if |
| * any of x, y or z is a complex number. |
| * Both macros call the chosen function with all additional arguments passed |
| * to them, as given by __VA_ARGS__. |
| * |
| * Note that these macros cannot be implemented with C's ?: operator, |
| * because the return type of the whole expression would incorrectly be long |
| * double complex regardless of the argument types. |
