--  This package provides the basic computational interface for the generic
--  elementary functions. This implementation is based on the glibc assembly
--  sources for the x86 glibc math library.

--  Note: there are two versions of this package. One using the 80-bit x86
--  long double format (which is this version), and one using 64-bit IEEE
--  double (see file a-numaux.ads). The latter version imports the C
--  routines directly.
