complexfunctioncladiv(complexx,complexy)CLADIV performs complex division in real arithmetic, avoiding unnecessary overflow. 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. ParametersX X is COMPLEX Y Y is COMPLEX The complex scalars X and Y.
