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.

Learn Scala from Scratch

## Problem Statement

In this challenge, your task is to convert the data type of an already existing variable using type casting. You are provided with a variable `oldType`  of type `Float` which needs to be type cast to `Double`.


### Input

The input is the variable `oldType`.

> `oldType` has already been declared for you.

### Output
The output will be the value assigned to `newType`.

### Sample Input
```
45F
```

### Sample Output
```
45D
```
### Test Yourself

Write your code in the given area. Try the exercise by yourself first, but if you get stuck, the solution has been provided. Good luck!
