# Number

Numbers are very straightforward data structures:

```
123
1.23
```

Most mathematical operators are designed to work with them

```
(2 ** 5.5 / 1 / 3 + 19) % 5 # 4.08494466531301
```

Note that numbers have what we call a “zero value”:
a value that evaluates to `false`

when casted to boolean:

```
!!0 # false
```

You can use bitwise operators on numbers, but bear in mind that they will be implicitely converted to integers:

```
1 ^ 1 # 0
1 ^ 0 # 1
1 ^ 0.9 # 1, as 0.9 is converted to 0
```

## Supported functions

### number()

Identity:

```
99.5.number() # 99.5
```

### int()

Rounds down the number to the closest integer:

```
10.3.int() # 10
```

### str()

Returns a string containing the number:

```
99.str() # "99"
```
