| Parameter | Description |
|---|---|
| f | Value to compute the arc-cosine for, in the range [-1,1]. |
float
Angle in radians whose cosine equals f, in the range [0, Pi].
Returns the arc-cosine of f - the angle in radians whose cosine is f.
For values of f outside of the [-1,1] range, this function will return NaN.
