D04AAF Example Program Results

 Four separate runs to calculate the first four odd order derivatives of
    f(x) = 0.5*exp(2.0*X-1.0) at x = 0.5.
 The exact results are 1, 4, 16 and 64

 Input parameters common to all four runs
   xval =  0.5    nder = -7    ifail = 0


 with step length   0.5000  the results are
