| -- 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 normal IEEE |
| -- 64-bit double format (which is this version), and one using 80-bit x86 |
| -- long double (see file 4onumaux.ads). |
| |
| package Ada.Numerics.Aux is |
| pragma Pure (Aux); |
| |
| -- This version omits the pragma linker_options ("-lm") since there is |
| -- no libm.a library for VxWorks. |
| |
| type Double is digits 15; |
| pragma Float_Representation (IEEE_Float, Double); |
| -- Type Double is the type used to call the C routines. Note that this |
| -- is IEEE format even when running on VMS with Vax_Float representation |
| -- since we use the IEEE version of the C library with VMS. |
