How to use nextUp(double d) in Java
Fouzia BashirThe static nextUp() method returns the floating-point value adjacent to N (argument value), but in the direction of positive infinity.
Syntax
static double nextUp(double N)
Parameters
N: The initial floating-point value
Return value
This function will return the adjacent floating-point value in the direction of positive infinity (+∞).
Special cases
Here are some special cases regarding nextUp():
- If the argument is NaN, then the result will also be NaN.
- If the argument is positive infinity, we will get positive infinity as a result.
- If we give zero as an argument, then the output will be
Double.MIN_VALUE.
Code
The following code illustrates how to use Math.nextUp().
import java.lang.*;
public class EdPresso {
public static void main(String[] args) {
// initialize the variables with double values
double n1 = 91868.321;
double n2 = 786;
// printing the next floating-point values directed towards positive infinity
System.out.println("Math.nextUp(" + n1 + ")= " + Math.nextUp(n1));
System.out.println("Math.nextUp(" + n2 + ")= " + Math.nextUp(n2));
}
}
- In lines 5 and 6,
n1andn2are declared and assigned values. - In lines 8 and 9, we pass
n1andn2to theMath.nextUpmethod.
