# acos

## Beschrijving

Geef de arc‑cosinus (inverse van cosinus) in graden.

| Naam | Beschrijving |
| --- | --- |
| Float:value | waarde waarvan de arc‑cosinus wordt berekend, in \[-1,+1\]. |

## Retourneert

De hoek in graden, in het interval \[0.0, 180.0\].

## Voorbeeld

```c
//De arc‑cosinus van 0.500000 is 60.000000 graden.
public OnGameModeInit()
{
    new Float:param, Float:result;
    param = 0.5;
    result = acos(param);
    printf("The arc cosine of %f is %f degrees.", param, result);
    return 1;
}
```
