  33 --  This package provides the basic computational interface for the generic
  34 --  elementary functions. This implementation is based on the glibc assembly
  35 --  sources for the x86 glibc math library.
  36
  37 --  Note: there are two versions of this package. One using the 80-bit x86
  38 --  long double format (which is this version), and one using 64-bit IEEE
  39 --  double (see file a-numaux.ads). The latter version imports the C
  40 --  routines directly.
