## Function/Subroutine Documentation

### subroutine dla_wwaddw (integer N, 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.
