Guild Wars 2

A reddit user, Boa-Noah, found a bug in the gems to gold exchange.

I have confirmed that it works. To replicate the bug, use custom exchange. Then type in the desired gold you want to have with a decimal or a fraction of a gold, ie. 78.2. Just make sure it hits 800 gems. After that, now incrementally increase the gold you want by a hundredth decimal, ie.78.21 or 78.22, until the bug triggers. You will now be able to exchange 2 gems for 78.22 gold, wow. For those trying this out, do not finalize the transaction. You might get banned, as this is an exploit, whether you know it or not as an exploit, when the banhammer hits, all who exchanged 2 gems for 78+ gold will get banned.

One decimal place is ok, two starts getting into the limitations of IEEE floats and the calls to the API get turned into nonsense.

Thus a request for 80.82 gold worth of gems returns “2” instead of something sensical. The trade happens entirely on the server and will deduct/deposit the correct amounts, it just won’t match up with the now-goofy UI state.

it’s just a display bug. The amount u will get is still correct despite wrong display, as also mentioned in the reddit post.

This has already been commented on by the Devs, it may show a strange, looks-like-an-exploit exchange, but actually exchanges the correct amount of gold/gems.
