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
!>    arithmetic, but not for decimal.

Parameters

[in]	N	!> N is INTEGER !> The length of vectors X, Y, and W. !>
[in,out]	X	!> X is DOUBLE PRECISION array, dimension (N) !> The first part of the doubled-single accumulation vector. !>
[in,out]	Y	!> Y is DOUBLE PRECISION array, dimension (N) !> The second part of the doubled-single accumulation vector. !>
[in]	W	!> W is DOUBLE PRECISION array, dimension (N) !> The vector to be added. !>
