The possibilities are infinite. No matter how far you carry out a number between zero and one, all that needs to be added is another number at the end. I will be limiting the possibilities for this discussion to one thousand by truncating it at the thousandth position. However, by doing so, I will be rounding up numbers greater than 5 in the ten-thousandth position and rounding down all numbers ending in 5 or less in the ten-thousandth position.
That doesn't mean much, but it may when you must decide what is the moral thing to do. It means that something which is .4996 moral and something else that is .5005 moral, will both round out to .500 moral. Even that doesn't mean much because we will all see what is moral differently than how others may see it, and we will each value morality differently when making decisions. For example, a narcissist will value morality less than they value ego and instant gratification. Even within the group categorized as narcissists, the value placed on morality will be weighted differently between members of the group.
