# Number methods

Although CSML differentiates between *Float* and *Integer*, all methods are available on all Number types. Hence, the *Number* type does not really exist but represents indifferently *Float* and *Integer*.

Given the automatic type inference, CSML will automatically try to map integers and floats to whichever type makes more sense in the context.

### .pow(Number)

Raise the target integer to the power of the given integer.

```cpp
number.pow(Number) => Number

// example
do val = 3
do val.pow(2) // 9
```

### .abs()

Return the absolute value of the target number.

```cpp
integer.abs() => Number

// example
do val = -42
do val.abs() // 42
```

### .cos(), .sin(), .tan()

Return the cosine, sine or tangent of the target number.

```cpp
float.cos() => Float
float.sin() => Float

// example
do val = 12.34
do val.cos() // 0,9744873988
do val.sin() // -0,224442219
do val.tan() // -0,2303182363
```

### .floor(), .ceil(), .round()

Round the number respectively down, up or using mathematical rounding.

```cpp
float.floor() => Integer
float.ceil() => Integer
float.round() => Integer

// example
do val = 10.5
do val.floor() // 10
do val.ceil() // 11
do val.round() // 11
```

### .precision(n)

```cpp
do val = 1.234567.precision(2) // 1.23
```
