Java Math Exercises: Get whole and fractional parts from a double value

Java Math Exercises: Exercise-2 with Solution

Write a Java program to get whole and fractional parts from a double value.

Sample Solution:

Java Code:

import java.util.*;
  public class Example2 {
  public static void main(String[] args) {
  double value = 12.56;
  double fractional_part = value % 1;
  double integral_part = value - fractional_part;  
  System.out.print("\nOriginal value: "+value);
  System.out.print("\nIntegral part: "+integral_part);
  System.out.print("\nFractional part: "+fractional_part);
  System.out.println();  
  }
}

Sample Output:

Original value: 12.56                                                  
Integral part: 12.0                                                    
Fractional part: 0.5600000000000005
