Simple rotation question

Please help!!

I failed geometry at school, and certainly haven't improved since then. I don't understand ANY of the Wiki entries about rotation, nor the posts I have found in here :o


I want to know whether my prim has been turned "upside down", ie: its x or y rotation will be more than 90 degrees.

My best attempt is still failing; it returns "0.000" no matter what I think the answer should be.

PLEASE HELP!!

My best attempt:
CODE

default
{
    state_entry()
    {
        rotation myrotation = llGetRot();
        llVecMag(<myrotation.x, myrotation.y, 0>);
        
        
        if (llVecMag(<myrotation.x, myrotation.y, 0>) > PI_BY_TWO) {
        
        llSay(0, "greater");
    }
        
     else
     {   
        llSay(0, (string)myrotation.y);
    }
}
}


Thanks ....

Quickest way that I can think of:
CODE

am_i_upside_down()
{
   vector up = llRot2Up(llGetRot());
   if (up.z > 0.0) llOwnerSay("I am facing upwards!");
   else llOwnerSay("I am facing downwards!");
}

Blimey, I didn't even know there *was* a Rot2Up!

Thanks a million!!! :D
