DLA_WWADDW adds a vector into a doubled-single vector.

Function/Subroutine Documentation

subroutine dla_wwaddw (integer N, double precision, dimension( * ) X, double precision, dimension( * ) Y, double precision, dimension( * ) W)

DLA_WWADDW adds a vector into a doubled-single vector.

Purpose: 



    DLA_WWADDW adds a vector W into a doubled-single vector (X, Y).


    This works for all extant IBM's hex and binary floating point


    arithmetics, but not for decimal.

Parameters:

N 



          N is INTEGER


            The length of vectors X, Y, and W.

X



          X is DOUBLE PRECISION array, dimension (N)


            The first part of the doubled-single accumulation vector.

Y



          Y is DOUBLE PRECISION array, dimension (N)


            The second part of the doubled-single accumulation vector.

W



          W is DOUBLE PRECISION array, dimension (N)


            The vector to be added.
