Summary

Function: float llAcos( float val );
172 Function ID
0.0 Delay
10.0 Energy

Returns a float that is the arccosine in radians of val

• float val – val must fall in the range [-1.0, 1.0]. (-1.0 <= val <= 1.0)

The returned value is in the range [0, PI]

Examples

// Touch the object with this script in it to see the arccosine of random numbers!
default
{
    touch_start(integer num)
    {
        float r = llFrand(2) - 1.0;
        llOwnerSay("The arccosine of " + (string)r + " is " + (string)llAcos(r));
    }
}
