Scala – Find the Power of a Number

Here, we will read an integer number and its power from the user and calculate the power of the number using scala.math.pow() function and print the result on the console screen.

Scala code to find the power of a number

The source code to calculate the power of a number is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to calculate the 
// power of a number

object Sample{  
    def main(args:Array[String]){  
        var num:Int    = 0;
        var p:Int      = 0;
        var res:Double = 0;
        print("Enter number: ")
        print("Enter power: ")
        res = scala.math.pow(num,p)
        println("Result: "+res);


Enter number: 5
Enter power: 3
Result: 125.0


In the above program, we used an object-oriented approach to create the program. Here, we created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we created three variables num, p, res that are initialized with 0. Then we read the value of the num and p variable from the user and then we calculated the power of a number using scala.math.pow() function. Here, scala.math is a package that contains the definition of pow() function.
