If you take a look at the display for trading gold for gems here: http://i.imgur.com/k2DfF.png you can see that the values are way off and that they don’t even make sense after 75. Those should actually be silver, not gold.
Now, if you look at gems for gold, the same problem is starting to appear: http://i.imgur.com/r3BoK.png
It looks to be a conversion error from the integer value to the gold, silver and copper value. It seems like it went unnoticed because the prices never reached 1g until recently. I wrote out a formula for my trading post scraper, you can see how it is supposed to work: http://i.imgur.com/xLlS8.png
Ninja Edit: For anyone wondering, the code is python and the int function automatically floors the value http://docs.python.org/library/functions.html#int
I guess it’s not a huge deal, but it should still be noted and fixed
