Flash bug? Rotate & set dimensions

[mr-money]

I have a MovieClip, which I have rotated. I then run:

thebox._width = 100;
thebox._height = 100;
trace(thebox._width+", "+thebox._height);

It returns... 93.5, 96.25........ why doesn't it return 100, 100?

Then... I run the script again

It returns... 99.1, 99.45

It keeps going up in increments, but never actually hits 100, 100.

I'm using Flash CS5 and Actionscript 2.0. What is going on?

By the way, the box is not rotated 90 degrees, 180 degrees, 270 degrees or anything nice like that. It's at a tilted angle.
