Java.lang.StrictMath.nextUp() Method

Description

The java.lang.StrictMath.nextUp(float f) method returns the floating-point value adjacent to f in the direction of positive infinity. This method is semantically equivalent to nextAfter(f, Float.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 Float.MIN_VALUE

Declaration

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

public static float nextUp(float f)

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) {
  
    float f1 = 35.9f , f2 = 58.8f;
              
    // returns the floating-point value adjacent to f1    
    float nextUpValue = StrictMath.nextUp(f1); 
    System.out.println("Next upper value of f1 : " + nextUpValue);
        
    // returns the floating-point value adjacent to f2
    nextUpValue = StrictMath.nextUp(f2); 
    System.out.println("Next upper value of f2 : " + nextUpValue);
  }
}

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

Next upper value of f1 : 35.900005
Next upper value of f2 : 58.800003
