SYNOPSIS

SUBROUTINE DLA_WWADDW(
N, X, Y, W )

    
IMPLICIT NONE

    
INTEGER N

    
DOUBLE PRECISION X( * ), Y( * ), W( * )

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.

ARGUMENTS

N (input) INTEGER
The length of vectors X, Y, and W. X, Y (input/output) DOUBLE PRECISION array, length N The doubled-single accumulation vector.
W (input) DOUBLE PRECISION array, length N
The vector to be added.
