## 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.
