Decimals are not kept or rounded iirc, but they are summed up for total figures for the empire. Thus, if you don't play with the slider you lose 0.9 beaker at maximum for the whole empire, not for each of the cities. I think same is for all other sliders. The bonuses are also there for the primary calculations. The bonuses are applied first for each city and then the result is summed and only then decimal discarded iirc. With slider maxed, you might actually lose something similar. For example, in older versions, if you have 7 beakers in a city with library, 7+7*0.25=8.75 which would have been 8 taken for the calculations. Now, this 8.75 goes to be added to total figures which does minimize the loss. So, previously, if you had 3 cities each making 8.75 beakers, you get total of 8*3=24 and now, you get 8.75*3=26.25 rounded to 26 regardless of slider setting.
