|
-- 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.
