Function/Subroutine Documentation

subroutine sladiv (realA, realB, realC, realD, realP, realQ)

SLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

Purpose: 



 SLADIV performs complex division in  real arithmetic


                       a + i*b


            p + i*q = ---------


                       c + i*d


 The algorithm is due to Robert L. Smith and can be found


 in D. Knuth, The art of Computer Programming, Vol.2, p.195
