Ah - memories...
Anyone remember "Quest" - the BASIC game that was included with the Dragon32?
My mission to pop down and teach the Warlock a few things was made infinitely simpler when I discovered currency trading lol... You see, the game's internal currency was "gold coins", and lots of things could be bought and sold in the game - including, interestingly enough, gold coins...
Rather than correct this oversight and actually treat coins as currency as opposed to a tradeable inventory item, the developer decided not stop any naughtiness by checking that for blaggards like me who would offer to sell a gold coin for the princely sum of two gold coins - by writing a test that effectively looked for price_per_coin < 2.
Had that test been price_per_coin <= 1, the Warlock would have remained a happy man. Sadly, I rather got into the habit of selling coins for 1.9999999999 gold coins - building up quite a little nest egg for myself in the space of five minutes, allowing me to purchase a rather impressive militia to wonder down to warlock central to explain what's what - usually in one very decisive battle...
Happy times - and an example I still use to this today to illustrate decent validation to junior developers...
