- Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

      @FunctionalInterface
      public interface DoubleBinaryOperator

  Represents an operation upon two `double`-valued operands and producing a `double`-valued result. This is the primitive type specialization of `BinaryOperator` for `double`.

  This is a functional interface whose functional method is `applyAsDouble(double, double)`.
