@preghenella. In the O2 converter for Run3 we are currently using some utilities from AliRoot for performing some truncation (AliMathBase::TruncateFloatFraction). I didn't use them for the moment cause I was not sure we wanted to go in that direction. I temporary removed the truncation. I wanted to know what you think about it.
I still have to check that the absence of truncation has the only effect of making the dataset bigger as I expect.
