Float to Absolute Value

Write a Java program to convert a floating value to an absolute value.

Sample Solution:

Java Code:

import java.util.*;
public class Example9 {

 public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Input a float number: ");
        float  x = in.nextFloat();  
        System.out.printf("The absolute value of %.2f is: %.2f",x, convert(x));
		System.out.printf("\n");
    }

    public static float convert(float n)
	{
		float absvalue = (n >= 0) ? n : -n;
		return absvalue;
	}
}

Sample Output:

Input a float number: 12.53                                            
The absolute value of 12.53 is: 12.53
