I know at least one large computer manufacturer who manages prices in several currencies using quite sophisticated rules for converting (based on stord conversion rates) and rounding to get "nice" prices (e.g. 299€ instead of 287,43€ which would result from applying the conversion rate).

So you wouldn't display prices in a shop before the user hits the "Order now" button?

Nightmare or not, this is *very* common when building shops or similar systems (B2B websites, procurement systems)
