*     .. Scalar Arguments ..
      DOUBLE PRECISION   X, Y
*     ..
*
*  Purpose
*  =======
*
*  PDDIFF returns the scalar difference X - Y. Similarly to the
*  BLAS tester, this routine allows for the possibility of computing a
*  more accurate difference if necessary.
*
*  Arguments
*  =========
*
*  X       (input) DOUBLE PRECISION
*          The real scalar X.
*
*  Y       (input) DOUBLE PRECISION
*          The real scalar Y.
*
*  =====================================================================
*
*     .. Executable Statements ..
*
      pddiff = x - y
*
      RETURN
*
*     End of PDDIFF
