Method Definition – def +(x: Double): Double

Returns – Returns the sum of this value and x.

Example #1:

// Scala program to explain the working
// of Long +(x: Double) method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Applying +(x: Double) function
        val result = (12.toLong).+(8:Double)

        // Displays output
        println(result)

    }
}

Output:

20.0

Example #2:

// Scala program to explain the working

object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Applying +(x: Double) function
        val result = (165.toLong).+(13:Double)

        // Displays output
        println(result)

    }
}
