Summary

Function: float llAsin( float val );

Returns a float that is the arcsine in radians of val

• float val must fall in the range [-1.0, 1.0]

The returned value is in the range [-PI_BY_TWO, PI_BY_TWO][1]

Examples

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