Rotation operator problems

[isx]

hi,i am testing rotation operator. it seems the value is not in degrees. when i put 90 it will rotate way more than it should be.
another problem when i using "object align" with animated object. i cannot get correct offset animation.
i tried time setting using "event age","on event entry(interval)","Continues", all didn't work.
but if i just animate rotation operator value the animation offset correctly.
