Java.lang.StrictMath.nextUp() Method

Description

The java.lang.StrictMath.nextUp(double d) method returns the floating-point value adjacent to d in the direction of positive infinity. This method is semantically equivalent to nextAfter(d, Double.POSITIVE_INFINITY).A nextUp implementation may run faster than its equivalent nextAfter call. It include these cases:

• If either argument is a NaN, then NaN is returned.
• If the argument is positive infinity, the result is positive infinity.
• If the argument is zero, the result is Double.MIN_VALUE

Declaration

Following is the declaration for java.lang.StrictMath.nextUp() method

public static double nextUp(double d)

Parameters

• d -- This is the starting floating-point value.

Return Value

This method returns the adjacent floating-point value closer to positive infinity.

Exception

• NA

Example

The following example shows the usage of java.lang.StrictMath.nextUp() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

  public static void main(String[] args) {
  
    double d1 = 95.1200000000000 , d2 = 49.32;

    // returns the floating-point value adjacent to d1
    double nextUpValue = StrictMath.nextUp(d1); 
    System.out.println("Next upper value of d1 : " + nextUpValue);
        
    // returns the floating-point value adjacent to d2
    nextUpValue = StrictMath.nextUp(d2); 
    System.out.println("Next upper value of d2 : " + nextUpValue);
  }
}

Let us compile and run the above program, this will produce the following result:

Next upper value of d1 : 95.12000000000002
Next upper value of d2 : 49.32000000000001
