COMPLEX FUNCTION CLADIV( X, Y )
* * -- LAPACK auxiliary routine (version 3.2) -- * -- LAPACK is a software package provided by Univ. of Tennessee, -- * -- Univ. of California Berkeley, Univ. of Colorado Denver and NAG Ltd..-- * November 2006 * * .. Scalar Arguments .. COMPLEX X, Y * .. * * Purpose * ======= * * CLADIV := 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 * Y (input) COMPLEX * The complex scalars X and Y. * * ===================================================================== * * ..
