Guild Wars 2

If i wanted to convert 1g to gems, lets say i put in 1g, and it says 13 gem,
but if i put in 1g 1s, i get 14 gem.

instead of this tweaking everytime, what if gem have 13.X instead?

X can be gem shards, when they add to ten they carry over.

The price for Gold/Gem conversion is stupid right now as it is.
