Hello, and welcome back to our engaging journey with Kotlin! Today, we're going to cover an essential concept: Primitive Data Type Conversion in Kotlin.

Data conversions are common tasks in software development. For example, when you receive user input from a form in string format but need to store it as a different data type, it becomes necessary to convert that data. Understanding how to safely and effectively convert data types in Kotlin is an essential skill that you'll use frequently in your projects.

By the end of this lesson, you'll have learned the methods that Kotlin provides for data type conversion. Moreover, you'll know how to safely perform these conversions and handle common errors. Let's dive in!

In programming, data is stored and manipulated through variables. These variables have data types that determine the kinds of values they can hold. Occasionally, we need to convert data from one type to another; this is where the concept of data type conversion comes into play.

Data type conversion, also known as typecasting, is the process of transforming an entity from one data type to another.

There are two types of data type conversion:

• Implicit Conversion: Kotlin automatically performs this conversion when a smaller type is assigned to a larger type size. For instance, Int is a smaller type than Float, and Kotlin will implicitly convert Int to Float if needed. However, unlike some other languages, Kotlin doesn't support implicit conversions that could cause precision losses — like converting Long to or to .
