      • addAll

        public abstract float addAll()
        Adds all lane elements of this vector.

        This is a cross-lane reduction operation which applies the addition operation (+) to lane elements, and the identity value is 0.0.

        The value of a floating-point sum is a function both of the input values as well as the order of addition operations. The order of addition operations of this method is intentionally not defined to allow for JVM to generate optimal machine code for the underlying platform at runtime. If the platform supports a vector instruction to add all values in the vector, or if there is some other efficient machine code sequence, then the JVM has the option of generating this machine code. Otherwise, the default implementation of adding vectors sequentially from left to right is used. For this reason, the output of this method may vary for the same input values.

        Returns:
        the addition of all the lane elements of this vector
