DLADIV

Function/Subroutine Documentation

subroutine dladiv (double precisionA, double precisionB, double precisionC, double precisionD, double precisionP, double precisionQ)

DLADIV
Purpose:
 
 DLADIV 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
