Getting some strange results with rotation...

I just made this extremely simple script so I can see what values to expect.  Learned that top and left don't mean the top left corner of the token, but they mean the coordinates for the middle of the token. But with rotation I'm getting some strange results.  I rotate it to the right and got what I expected for awhile.  Then I started rotating it to the left and got -15 once.  Then I did it some more and I got 630 and other numbers.  I can't get it back to zero.  Am I doing something obviously wrong or could this be a bug with rotate? on("change:graphic", function(obj, prev) {          log(obj.get("top")+"/"+obj.get("left")+"/"+obj.get("rotation")); }); Here are some results from the log. "245/875/0" "245/875/-45" "245/875/225" "245/875/270" "245/875/315" "245/875/360" "245/875/315" "245/875/540" "245/875/360" "245/875/405" "245/875/450" "245/875/495" "245/875/540" Thanks for the help. I hope to quickly get better with javascript.  I've got an idea to help with rotation, but if it doesn't return proper results I'm stuck. :(

Not sure how I got the greater than 360deg.  Can't get it again after I set rotation to 0.  But I still get one thing definitely not right.  Rotating to the right gives results you would expect all the way to 27-deg.  Past that you get -1 to -89. "245,875 / 70 x 70 r:90" "245,875 / 70 x 70 r:135" "245,875 / 70 x 70 r:90" "245,875 / 70 x 70 r:180" "245,875 / 70 x 70 r:225" "245,875 / 70 x 70 r:270" "245,875 / 70 x 70 r:-45" "245,875 / 70 x 70 r:-83.12434926852556" "245,875 / 70 x 70 r:-3.2985713785899953"  

Rotating to the left causing all the numbers to start out negative?  And it goes past -360deg. 5,875 / 70 x 70 r:0" "245,875 / 70 x 70 r:-45" "245,875 / 70 x 70 r:-90" "245,875 / 70 x 70 r:-135" "245,875 / 70 x 70 r:-180" "245,875 / 70 x 70 r:-225" "245,875 / 70 x 70 r:-270" "245,875 / 70 x 70 r:-315" "245,875 / 70 x 70 r:-360" "245,875 / 70 x 70 r:-405"

Ya, but from my tests there are a bunch of exceptions.  Nothing seems to make a lot of sense.  I even go some results up at 730deg.  Its going to be hard to make a script that does rotating whith so many possible outcomes to simply rotating the token. :(  Just my luck, the firsst thing I try is a bit wonky. :)  I'll keep on plugging away. Thanks!
