Scala – Read and Print Float Value

Here, we will create a float variable. Then we will read the value of the float variable and print the value of the variable on the console screen.

Scala code to read the value of float variable

The source code to read the value of the float variable is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to read the value of 
// float variable

object Sample{  
    def main(args: Array[String]): Unit = {
        var num:Float=0
          
        print("Enter number: ")
        num = scala.io.StdIn.readFloat()
        
        println("Entered number: "+num)
    }  
}

Output

Enter number: 3.14
Entered number: 3.14

Explanation

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 a float variable num. Then we read the value of variable num using the scala.io.StdIn.readFloat() function. After that, we printed the entered number on the console screen.
