> Frequently when incrementing or decrementing a number, one needs to compare it to a limit. For example in loops.
> At present that requires two calls:
> MutableInt.decrement()
> MutableInt.getValue()
> It would be convenient to have a method that combined the two.
> c.f. AtomicInteger.decrementAndGet()
> There is less likelihood of needing these methods for other Mutable Number types as they are not often used in loops.
