How to do it...

Let's understand how to convert one data type into another by following the steps below:

1. Let's try a very basic example—trying to convert an Int to Long and Float:

fun main(args: Array<String>) {    var a = 1    var b: Float = a.toFloat()    var c = a.toLong()    println("$a is Int while $b is Float and $c is Long")}

2. Similarly, Long can be converted to Float and Int, like this:

fun main(args: Array<String>) {    var a = 1000000000000000000L    var b: Float = a.toFloat()    var c = a.toInt()    println("$a is Long while $b is Float and $c is Integer")}

The output of this code is as shown:

1000000000000000000 is Long while 9.9999998E17 is Float and -1486618624 is Integer

3. Let's try a more interesting conversion with Byte, Int, and Strings:
