Hi, I am interested in your opinion. I use FixedDecimal for computing currency amounts. This works fine. When storing the amounts with voyage into mongo (I have a lot of them!!!), normally, one currency amount would be stored into mongo as follows: "vatAmountEUR": { "#instanceOf": "FixedDecimal", "negative": false, "number": NumberInt(90280), "part1": NumberInt(9), "part2": NumberInt(280), "scale": NumberInt(4) } I think, this is a lot of stuff for one single value. I tend to convert the FixedDecimal into a Float for storing it. In this case, it would be like this: "vatAmountEUR": 0.7196 When loading, I immediately re-convert it into a FixedDecimal. I would do NO computing with the float(!!). What is your opinion about this (rounding issues, performance, database size etc.)? Do you think, there is something against it? What would you do?
