@Felthry the exchange rate was constant, we switched from francs to euros and the franc was no longer in use
@codl well, it still is in switzerland as we understand it
@Felthry that's a different currency, they have swiss francs, we had french francs
@Felthry anyway the point was that people still thought in francs and so every calculator even the tiniest keychain calculator made between like 2001 and 2006 had a conversion button
@codl yeah i can understand that if you switch currencies it would take a while to get used ot it
@Felthry @codl you usually type in the exchange rate that you got from the business pages in the newspaper at the start of the day and it saves that for all the conversions
