Implementing algorithms like Dijkstra make me question whether or not POSITIVE_INFINITY < POSITIVE_INFINITY. It resembles an infinity in its mathematical behavior. However, you can use MAX_VALUE in many situations like a merge sort were it can be used as a "sentinel value". How exactly to have operations on infinity work depends on your domain. In mathematics, we have a set of real numbers and a set of integers. It's probably simplest if you handle the infinite cases first, then reuse the existing operations on finite values of the original type. And furthermore BigInteger operations are optimized (for instance using special CPU instructions) On a sidenote if people mean any number, they sometimes mean any resonable number. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. There's also a library that actually has fields POSITIVE_INFINITY and NEGATIVE_INFINITY, but they are really just new names for MAX_VALUE and MIN_VALUE. This value is obtained by dividing -1.0 by 0.0. The Double and Float types have the POSITIVE_INFINITY constant. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The Number.POSITIVE_INFINITY value behaves slightly differently than mathematical infinity: Any positive value, including POSITIVE_INFINITY, multiplied by POSITIVE_INFINITY is POSITIVE_INFINITY. Namely to subclass the class Number. If for example, you wanted to return the smallest of a pair and you happened to compare the sentinel with the value 2147483647 occurring in your list.

There might or might not be a general pattern to whether or not it's beneficial to adopt a convention of handling left-hand-side infinities before right-hand-side infinities or vice versa; I can't tell without trying it out, but for less-than-or-equal (lteq) I think it's simpler to look at right-hand-side infinity first. C90FDAP2f . Which is how I understand the "question". If so, you can get a result that's functionally nearly the same as POSITIVE_INFINITY by using the MAX_VALUE field of the Integer class: (And for NEGATIVE_INFINITY you could use MIN_VALUE.)
