| -- This package provides the basic computational interface for the |
| -- generic elementary functions. With the intrinsic version, the |
| -- compiler can use its knowledge of the functions to select the most |
| -- suitable implementation. It is thus quite portable. These |
| -- interfaces are suitable for cases in which Float and C's float |
| -- share the same representation. |
