35 -- This package provides the basic computational interface for the generic
36 -- elementary functions. The C library version interfaces with the routines
37 -- in the C mathematical library, and is thus quite portable, although it may
38 -- not necessarily meet the requirements for accuracy in the numerics annex.
39 -- One advantage of using this package is that it will interface directly to
40 -- hardware instructions, such as the those provided on the Intel x86.
42 -- Note: there are two versions of this package. One using the normal IEEE
43 -- 64-bit double format (which is this version), and one using 80-bit x86
44 -- long double (see file 4onumaux.ads).
