Their maximum values are closer to infinity than the maximum value of Integers, but not much closer. Can the Spiritual Weapon spell be used as cover? I think Integer.MAX_VALUE an achievable value, so it can be matched by a representable number of digits. In java, we have inbuilt constant variables which store the infinity value and it isavailable in java.lang package and it is a default package that is automatically imported in the java program. But It's probably simplest if you handle the infinite cases first, then reuse the existing operations on finite values of the original type. Also, as noted in the comments below, incrementing positive infinity will wrap you back around to negative numbers (and decrementing negative infinity will wrap you back to positive). I just need help clearing it up because I don't think I'm going in the right direction. 6 How to define the value of infinity in Java?
