Are there conventions to indicate a new item in a list? The idea is to create a new type which has all the same values as some already existing type, plus one special value whichas far as you can tell through public methodsacts exactly the way you want infinity to act, e.g. How to Use the JavaScript Fetch API to Get Data? Operations on BigInteger 's are slower but will work, regardless of the number (as long as it is an integer). What's wrong with my argument? An example of data being processed may be a unique identifier stored in a cookie. Since the class Number is not final, here is an I'm using null to represent infinity here, since that seems the most straightforward in Java. There will of course be some functional differences, e.g., when comparing myInf to a value that happens to be MAX_VALUE: clearly this number isn't less than myInf. Maybe examining it's source might be useful when creating a simpler version of it : http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/math/BigInteger.java.
