*     Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
*     Courant Institute, Argonne National Lab, and Rice University
*     October 31, 1992

*     .. Scalar Arguments ..
      COMPLEX*16         X, Y
*     ..
*
*  Purpose
*  =======
*
*  ZLADIV := X / Y, where X and Y are complex.  The computation of X / Y
*  will not overflow on an intermediary step unless the results
*  overflows.
*
*  Arguments
*  =========
*
*  X       (input) COMPLEX*16
*  Y       (input) COMPLEX*16
*          The complex scalars X and Y.
