Returns the arc-sine, in radians, of Value.

Parameters

Value (float): A floating-point value.

Technical Details

Return Type: float
Energy: 10

// 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));
    }
}

Caveats

The input value must fall in the range [-1.0, 1.0]
The returned value is in the range [-PI_BY_TWO, PI_BY_TWO] radians, or NaN (not a number) if the parameter is out of range
Triggers a Math Error for complex results if not compiled in Mono
