How to find smallest of two numbers in Kotlin

In this tutorial, you shall learn how to find the smallest of given two numbers in Kotlin, with the help of example programs.

Kotlin Find smallest of two numbers

To find the smallest of given two numbers in Kotlin, we can use Greater-than or Less-than operator and compare the two numbers.

If a and b are given two numbers, the condition to check if a is less than b is

a < b

The above condition returns true if a is less than b, or else, it returns false.

Program

In the following program, we read two numbers from user and store them in a and b, then use Less-than comparison operator to find the smallest of a and b.

Main.kt

fun main() {
    print("Enter first number : ")
    val a = readLine()!!.toDouble()
    print("Enter second number : ")
    val b = readLine()!!.toDouble()

    if (a < b) {
        print("$a is the smallest of $a and $b")
    } else {
        print("$b is the smallest of $a and $b")
    }
}

Output #1

Enter first number : 4
Enter second number : 9
4.0 is the smallest of 4.0 and 9.0

Output #2

Enter first number : 8
Enter second number : 5
5.0 is the smallest of 8.0 and 5.0
