A question about auction orders

[humanwoman]

I put an order on the auction for the amount 42.23 ped at MU 105.7%.

It was matched at MU 104.1%, and I got the message that "money returned for this trade is 0.63 ped".

I actually thought that this returned amount is 42.23*(105.7-104.1), but that would be 0.675, not 0.63



Sooo, does anyone know how the returned amount is calculated?

42.23 / 105.70% ~= 39.95 PED TT.
39.95 * 104.10% ~= 41.59 PED.
42.23 - 41.59 = 0.64 PED.

64 PEC is pretty close to 63 PEC.

The UI displays limited precision in both percentages and absolute amounts.

42.23 was the TT value

anyway, it's probably a rounding error
