Question

Write a program that accepts a number as input, and prints just the decimal portion.

Example:

Enter a number: 15.789
Output:

0.789

Answer 1

Explanation:

The below code is written in python language  as there is no restriction about language.

Code:

System.in.println("Enter a number: %n" n);

System.out.printf("n %% 1= %.3f%n", n % 1);

System.out.printf("n - Math.floor(n) = %.3f%n", n - Math.floor(n));

System.out.printf("n - (int)n= %.3f%n", n - (int)n);

Code simulation :

Enter a number: 15.789

Output

n % 1= 0.789

n - Math.floor(n) = 0.789

n - (int)n= 0.789
