SLA_WWADDW
Purpose
=======
SLA_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.
Arguments
=========
N (input) INTEGER
The length of vectors X, Y, and W.
X (input/output) REAL array, dimension (N)
The first part of the doubled-single accumulation vector.
Y (input/output) REAL array, dimension (N)
The second part of the doubled-single accumulation vector.
W (input) REAL array, dimension (N)
The vector to be added.
