If you haven't used generics before (or even if you have), it may not be
obvious that the functions are already available. Visit
 <http://sw-eng.falls-church.va.us/cgi-bin/webada/surfada?file=/opt/gnu/adainclude/a-nuelfu.ads#L20>
which is the predefined package Ada.Numerics.Elementary_Functions. However,
to see the list of functions (including "**") follow the link to the
generic as suggested above. The whole list of predefined packages can
be surfed at:
