Kotlin Program – Average of Two Numbers

Kotlin – Average of two numbers

In Kotlin, you can find the average of given two numbers by first finding their using Arithmetic Addition operator +, and the dividing the sum by 2 using Arithmetic Division operator.

The two arguments can be of any numeric data type.

For example, if a and b are the two given numbers, then the expression to find their average is

(a + b) / 2

Examples

Average of the two numbers 10 and 20

In the following example, we take two number values in a and b, and find their average using the above specified expression.

Kotlin Program

fun main() {
    val a = 10
    val b = 20
    val average = (a + b) / 2
    println("Average : $average")
}

Output

Average : 15

Explanation

Average = (10 + 20) / 2
        = (30) / 2
        = 15

Average of the two numbers 3.14 and 1.20

In the following example, we take two floating point numbers in a and b, and find their average.

Kotlin Program

fun main() {
    val a = 3.14
    val b = 1.20
    val average = (a + b) / 2
    println("Average : $average")
}

Output

Average : 2.17

Explanation

Average = (3.14 + 1.2) / 2
        = (4.34) / 2
        = 2.14
