| -- This package provides the basic computational interface for the generic |
| -- elementary functions. The C library version interfaces with the routines |
| -- in the C mathematical library, and is thus quite portable, although it may |
| -- not necessarily meet the requirements for accuracy in the numerics annex. |
| -- One advantage of using this package is that it will interface directly to |
| -- hardware instructions, such as the those provided on the Intel x86. |
| |
| -- Note: there are two versions of this package. One using the 80-bit x86 |
| -- long double format (which is this version), and one using 64-bit IEEE |
| -- double (see file a-numaux.ads). |
