In this simple assignment you are given a number and have to make it negative. But maybe the number is already negative?

**Example:**
``` c
makeNegative(1); // return -1
makeNegative(-5); // return -5
makeNegative(0); // return 0
```
``` cfml
makeNegative(1); // return -1
makeNegative(-5); // return -5
makeNegative(0); // return 0
```
``` csharp
Kata.MakeNegative(1); // return -1
Kata.MakeNegative(-5); // return -5
Kata.MakeNegative(0); // return 0
```
``` java
Kata.makeNegative(1); // return -1
Kata.makeNegative(-5); // return -5
Kata.makeNegative(0); // return 0
```
``` python
make_negative(1);  # return -1
make_negative(-5); # return -5
make_negative(0);  # return 0
```
``` javascript
makeNegative(1); // return -1
makeNegative(-5); // return -5
makeNegative(0); // return 0
makeNegative(0.12); // return -0.12
```
``` typescript
makeNegative(1); // return -1
makeNegative(-5); // return -5
makeNegative(0); // return 0
```
``` cpp
makeNegative(1); // return -1
makeNegative(-5); // return -5
makeNegative(0); // return 0
```
``` haskell
makeNegative    1 -- return -1
makeNegative (-5) -- return -5
makeNegative    0 -- return 0
makeNegative 0.12 -- return -0.12
```
``` ruby
makeNegative(1); # return -1
makeNegative(-5); # return -5
makeNegative(0); # return 0
```
``` coffeescript
makeNegative 1    # return -1
makeNegative -5   # return -5
makeNegative 0    # return 0
```
``` elixir
make_negative 1    # return -1
make_negative -5   # return -5
make_negative 0    # return 0
```
``` go
MakeNegative(1)    # return -1
MakeNegative(-5)   # return -5
MakeNegative(0)    # return 0
```
``` julia
Kata.makeNegative(1)  # return -1
Kata.makeNegative(-5) # return -5
Kata.makeNegative(0)  # return 0
```
``` kotlin
Kata().makeNegative(1)  // return -1
Kata().makeNegative(-5) // return -5
Kata().makeNegative(0)  // return 0
```
``` asm
make_negative(1);    // return -1
make_negative(-5);   // return -5
make_negative(0);    // return 0
```
``` groovy
Kata.makeNegative(1)    // return -1
Kata.makeNegative(-5)   // return -5
Kata.makeNegative(0)    // return 0
```
``` php
makeNegative(1)    // return -1
makeNegative(-5)   // return -5
makeNegative(0)    // return 0
makeNegative(0.12) // return -0.12
```
```racket
(make-negative 1)    ; -1
(make-negative -5)   ; -5
(make-negative 0)    ; 0
(make-negative 0.12) ; -0.12
```

**Notes:**

- The number can be negative already, in which case no change is required.
- Zero (0) is not checked for any specific sign. Negative zeros make no mathematical sense.
