BCD tables only load in the browser with JavaScript enabled. In the computer world, we need a memory location where we can store the values for these sets, and this location must be finite as the memory of a computer is finite. Instead, Java assigns to the floating-point result one of the special values listed in the table below. The answer to the question is "No. Example 7: When we divide Number.POSITIVE_INFINITY by any positive number except Number.POSITIVE_INFINITY, result is Number.POSITIVE_INFINITY. We can also simply divide a number with zero to implement infinity in Java. We can only store integer numbers that fit in the memory location that we chose. I'm not a very seasoned coder. 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.

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 isnt less than myInf. Every double variable with this bitwise value contains negative infinity. If you want to add arithmetic operations, decide what they should do, then implement that. When divided by itself or positive infinity, negative infinity return NaN. Connect and share knowledge within a single location that is structured and easy to search. 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: Integer myInf = Integer.MAX_VALUE; (And for NEGATIVE_INFINITY you could use MIN_VALUE.)

It's probably simplest if you handle the infinite cases first, then reuse the existing operations on finite values of the original type. To exemplify, let's take a double value d and check the results of the following divisions by zero: In this article, we explored the concept and usage of positive and negative infinity in Java. If so, you can get a result thats 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.) In mathematics, we have a set of real numbers and a set of integers. Enable JavaScript to view data.
