We assume that the effective unit cost in the orderbook is valid and that that amount was paid and also that any remainder will be close enough in effective unit cost to not matter. At the edge cases, this will probably be not true and maybe some orders wont be practically fillable when reduced to fractional state. However, the original pubkey that created the offer can always reclaim it.
