Thanks for your time with this Norm. For now I have to rest and sleep so I will try again tomorrow.
I cannot work out the toString() method still. But my main issue here is how to get it to return the biggest value which we know to be 2.16
That doesn't mean I don't want to work out what you want me to do the toString() method for or how to do it because I am curious now. But I am spending more time on this than I should and have other assignments waiting to be done. I will not give up on this, but need to prioritise.
