code: public Vector4f set(Vector4dc v) {
          return set((float) v.x(), (float) v.y(), (float) v.z(), (float) v.w());
      }
docs: Set this {@link Vector4f} to the values of the given <code>v</code>.
  <p>
  Note that due to the given vector <code>v</code> storing the components in double-precision,
  there is the possibility to lose precision.
  
  @param v
  the vector whose values will be copied into this
