# Round Floats To Integers
|
|
|
|
The
|
|
[`Float.round/2`](http://elixir-lang.org/docs/stable/elixir/Float.html#round/2)
|
|
function allows you to round floating point numbers. The result is another
|
|
floating point number.
|
|
|
|
```elixir
|
|
> Float.round(1.5)
|
|
2.0
|
|
> Float.round(1.3)
|
|
1.0
|
|
```
|
|
|
|
If, instead, you always want an integer as the result of rounding, you can
|
|
use `Kernel`'s version of a rounding function:
|
|
|
|
```elixir
|
|
> Kernel.round(1.5)
|
|
2
|
|
> Kernel.round(1.3)
|
|
1
|
|
```
|
|
|
|
The
|
|
[`Kernel.round/1`](http://elixir-lang.org/docs/stable/elixir/Kernel.html#round/1)
|
|
function accepts both integers and floats, and always returns an integer.
|
|
Additionally, it can be used in guard tests.
