Function/Subroutine Documentation

subroutine dla_wwaddw (integerN, 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.
