36 -- This package provides the basic computational interface for the generic
37 -- elementary functions. The C library version interfaces with the routines
38 -- in the C mathematical library, and is thus quite portable, although it may
39 -- not necessarily meet the requirements for accuracy in the numerics annex.
40 -- One advantage of using this package is that it will interface directly to
41 -- hardware instructions, such as the those provided on the Intel x86.
43 -- Note: there are two versions of this package. One using the normal IEEE
44 -- 64-bit double format (which is this version), and one using 80-bit x86
45 -- long double (see file 4onumaux.ads).
47 package Ada.Numerics.Aux is
50 pragma Linker_Options ("-lm");
52 type Double is digits 15;
53 pragma Float_Representation (IEEE_Float, Double);
54 -- Type Double is the type used to call the C routines. Note that this
55 -- is IEEE format even when running on VMS with Vax_Float representation
56 -- since we use the IEEE version of the C library with VMS.
