| -- 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. |
| |
| -- This is the VMS version |
| |
| package Ada.Numerics.Aux is |
| pragma Pure; |
| |
| 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_Native representation |
| -- since we use the IEEE version of the C library with VMS. |
| |
| -- We import these functions directly from C. Note that we label them |
| -- all as pure functions, because indeed all of them are in fact pure! |
