Course of Raku / Essentials / Numbers / Exercises / The last digit

# Solution: The last digit

The idea of the solution of this task is to use modulo division by 10 to get the last digit of the number.

## Code

Here is the solution:

```
my $n = prompt 'Enter a number: ';
my $d = $n % 10;
say "The last digit of $n is $d.";
```

🦋 Find the program in the file the-last-digit.raku.

## Output

Run the program and enter a positive integer:

```
$ raku exercises/numbers/the-last-digit.raku
Enter a number: 1234
The last digit of 1234 is 4.
```

## Comment

Note that this does not work as expected with negative numbers, as, for example, `-11 % 10`

is `9`

, not `1`

.
