  36 --  elementary functions. This implementation is based on the glibc assembly
  37 --  sources for the x86 glibc math library.

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