Ruby Example: Write a program to demonstrate the phase() function.
Submitted by Nidhi, on December 14, 2021

Problem Solution:

In this program, we will create 2 variables and initialize them with some values. Then we will use the phase() function with created variables. The phase() function returns 0 if the variable contains a positive value otherwise it returns the value of "pi" which is 3.141592653589793.

Program/Source Code:

The source code to demonstrate the phase() function is given below. The given program is compiled and executed successfully.

# Ruby program to demonstrate the 
# phase() function

num1 = 10;
num2 = -10;

print num1.phase(),"\n";
print num2.phase(),"\n";

Output:

0
3.141592653589793

Explanation:

In the above program, we created two variables num1, num2, and initialized 10,-10 respectively. Then we used the phase() function with both variables to print the result. The phase() function returns 0, if value of variable is positive otherwise it returns value 3.141592653589793.
