The negative infinity in JavaScript is a constant value that is used to represent a value that is the lowest available. The 32 bits float type and also the 64 bits double type supports this in Java. Its purpose is modularization of globals. 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.) It may be more involved, but it has the advantage of working for any type that doesn't define its own infinity.
