Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

# Task

In this challenge, you were provided with a variable that was previously defined to have a data type `Float` and you were asked to type cast it to a `Double`.

# Solution

Let's look at how we should go about this.

* The first thing is deciding the variable name, which you were told to keep as `newType`.

* As type casting is from `Float` to `Double` when defining `newType` specify the data type as `Double`.

* The last step is simply assigning `newType` the value of `oldType`.

```
val newType: Double = oldType
```

You can find the complete solution below:

In the following lesson, we will go over the solution of the challenge: Type Casting.
