In the following example, the variable bigNumber is assigned a value that is larger than the maximum value. I'm using null to represent infinity here, since that seems the most straightforward 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: Integer myInf = Integer.MAX_VALUE; (And for NEGATIVE_INFINITY you could use MIN_VALUE.) While Java doesn't provide an integral bit pattern to represent an infinite value, you might be able to make use of Integer.MAX_VALUE for your problem. nguyenxndaidev September 30, 2022, 4:45pm #1. The wrapper class Integer defines two constants that hold these values: Integer.MIN_VALUE and Integer.MAX_VALUE. 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. It uses an bitarray with varying length. Positive infinity means going to infinity in the positive direction -- going into values that are larger and larger in magnitude in the positive direction. is there a chinese version of ex. Because POSITIVE_INFINITY is a static property of Number, you always use it as Number.POSITIVE_INFINITY, rather than as a property of a number value. Otherwise, return the largest possible positive floating point number. In this tutorial, we are learning how to implement infinity in Java. Number.MIN_VALUE The smallest positive representable numberthat is, the positive number closest to zero (without actually being zero). Since the class Number is not final, here is an Note: JavaScript shows the NEGATIVE_INFINITY value as -Infinity. I don't think I'm approaching this the right way. The Number.POSITIVE_INFINITY static data property represents the positive Infinity value. Note that a similar value exists for longs - Long.MAX_VALUE. The number of bits used to represent a double value. Since there are only two values, we could use the singleton pattern: Somehow I think the remaining methods intValue(), longValue() Note that integer division by zero would throw an ArithmeticException thus your line would have to be 4.0/0, 4/0.0 or 4.0/0.0 since 4 and 0 are integers and thus result in integer math. How exactly to have operations on infinity work depends on your domain. Type the following to define a double (or float) with a value of positive or negative infinity: double pInfiniteDouble = Double.POSITIVE_INFINITY; double nInfiniteDouble = Double.NEGATIVE_INFINITY; float pInfiniteFloat = Float.POSITIVE_INFINITY; float nInfiniteFloat = Float.NEGATIVE_INFINITY; Check to see if a double or float has a value of infinity using the "isInfinite()" method: pInfiniteDouble.isInfinite(); nInfiniteDouble.isInfinite(); pInfiniteFloat.isInfinite(); nInfiniteFloat.isInfinite(); Techwalla may earn compensation through affiliate links in this story.
