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 a variable `quotient` which you had to print after embedding it in a string and formatting it in such a way that the output would only display it up to **3** decimal places.

## Solution

The first thing you had to figure out was that the `f` string interpolator can be used to format strings.

```
print(f....)
```


In the print statement, you had to write the required string and where ever you wanted to embed a variable, you had to insert a `$` followed by the variable name, `quotient`. 

```
println(f"The quotient is $quotient")
```

Next, you needed to format the string by creating your format specifier based on your requirements. Because quotients are usually of the type `Float`, you need to use the `f` conversion-character which is preceded by the number of decimal places you wanted to display, i.e. `.3`. Finally, `%` is the start of the format specifier

```
println(f"The quotient is $quotient%.3f")
```

You can find the complete solution below:

>You were required to write the code on **line 3**.
