At the time i was assuming that there was more to the trick than just 
adding 0.5 (fixed point) before right-shifting it. If not, then yes, 
this is still included in the mmi version. The actual rounding values 
made me suspect there was more going on ; after a lot of reshufling of 
the code and measuring the accuracy, the rounding values are now also 
different btw.
