the trick to add 0.25 may not be necessary in this case,
but the reason why I suggest using it is for field rendering.
In field rendering, the frame number in xsi will be 1.0, 1.5, 2.0, 2.5,
etc. If you round to nearest frame with +0.25,
you'll end up with frame numbers 1, 1, 2, 2. If you use
+0.5, you'll end up with frame numbers 1,2,2,3. In other words +0.25
rounds down each field time to the frame number.

(LONG)(
1.6 + 0.25) =>
1
(LONG)(1.6
+ 0.5) => 2
The
correct round of 1.6 is 2, so adding 0.25 gives an incorrect round.
Surely?
