# Round

Rounds to the nearest whole number. 0.5 is rounded up.

```javascript
(module
  (func $fract (export "fract") (param $x f32) (result f32)
    (f32.sub
      (get_local $x)
      (f32.floor (get_local $x))
    )
  )
  (func $round (export "round") (param $x f32) (result f32)
    get_local $x
    call $fract
    f32.const 0.5
    f32.ge
    if $i0
      get_local $x
      f32.ceil 
      return
    end
    get_local $x
    f32.floor 
  )
)
```
