Detailed Description

Function Documentation

complex function cladiv (complex x, complex y)

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.
Parameters

X

          X is COMPLEX

Y

          Y is COMPLEX
          The complex scalars X and Y.
