          The special functions portion of Commons-Math contains several useful functions not
          provided by <code>java.lang.Math</code>.  These functions mostly serve as building blocks
          for other portions of Commons-Math but, as others may find them useful as stand-alone
          methods, these special functions were included as part of the Commons-Math public API.
