Note, however, that NaN would be more appropriate in such a case. 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.) Never the less, it's not quite the same as Infinity? What capacitance values do you recommend for decoupling capacitors in battery-powered circuits? It uses an bitarray with varying length. Let's declare a double variable called positiveInfinity and assign to it the value Double.POSITIVE_INFINITY and another double variable negativeInfinity and assign to it value Double.NEGATIVE_INFINITY. The Double and Float types have the POSITIVE_INFINITY constant. . To learn more, see our tips on writing great answers. BCD tables only load in the browser with JavaScript enabled. I found another implementation for the infinity in the Java documentation, for the boolean and double types. 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.) 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. Throws: NumberFormatException - signum is not one of the three legal values (-1, 0, and 1), or signum is 0 and magnitude contains one or more . Negative infinity means going to infinity in the negative direction -- going into values that are larger and larger in magnitude in the negative direction. But, by taking the advantage of hint i.e. The integer types in Java use either unsigned binary (for char) or two's complement signed representation. Enable JavaScript to view data. If you divide a number by zero, and the sign of both numbers is the same, the result is positive infinity. Negative infinity, when divided by any positive number (apart from positive infinity) is negative infinity. Let's see the mathematical operations with infinity and a positive number: Now, let's see the mathematical operations with infinity and a negative number: There are a few rules of thumb to remember these operations better: The division by zero is a special case of division because it produces negative and positive infinity values.
