la_wwaddw - la_wwaddw: add to double-double or single-single vector


subroutine cla_wwaddw (n, x, y, w)
CLA_WWADDW adds a vector into a doubled-single vector. subroutine dla_wwaddw (n, x, y, w)
DLA_WWADDW adds a vector into a doubled-single vector. subroutine sla_wwaddw (n, x, y, w)
SLA_WWADDW adds a vector into a doubled-single vector. subroutine zla_wwaddw (n, x, y, w)
ZLA_WWADDW adds a vector into a doubled-single vector.

CLA_WWADDW adds a vector into a doubled-single vector.

Purpose:

    CLA_WWADDW adds a vector W into a doubled-single vector (X, Y).
    This works for all extant IBM's hex and binary floating point
    arithmetic, but not for decimal.

Parameters

N 

          N is INTEGER
            The length of vectors X, Y, and W.

X

          X is COMPLEX array, dimension (N)
            The first part of the doubled-single accumulation vector.

Y

          Y is COMPLEX array, dimension (N)
            The second part of the doubled-single accumulation vector.

W

          W is COMPLEX array, dimension (N)
            The vector to be added.
