Hello I noticed that game is sold for 94,99 pln with discount -50% but calculation is wrong because when you divide regular price you get the result 94,945 so if you round this up youll get 94,95 ... and this is current price on Steam but on gog its 94,99 - so steam calculated this properly and cutting gog

It's the other way around - 94.99 is 50% (rounded) of 189.89, they set the final price and see what percentage it is. Apart from that - time of both my answer and your post is worth more than a difference in price itself... Why did I even write the answer :S
