Ruby program to get the denominator from a rational number

Program/Source Code:

The source code to get the denominator from a rational number is given below. The given program is compiled and executed successfully.

# Ruby program to get the denominator 
# from a rational number

num1 = Rational(21, 7);
num2 = Rational(-7, 20);
num3 = Rational(21);

print "Num1 denominator: "  ,num1.denominator();
print "\nNum2 denominator: ",num2.denominator();
print "\nNum3 denominator: ",num3.denominator();

Output:

Num1 denominator: 1
Num2 denominator: 20
Num3 denominator: 1

Explanation:

In the above program, we created three variables num1, num2, num3 and initialized them with rational numbers. Then we got the denominator from the given rational number using the Rational() library function and printed the result.
