Bukkit

I was trying to create a chestshop with a decimal place in it but it always returns "invalid amount!" i have seen pictures of people using decimals in their signs however i cannot find any information on why it would not allow a decimal place. ive spent several hours scouring the internet trying to find a solution to this problem but it seems that no person on the planet has any idea how to use it more than telling you the command to add a buy/sell price. the only response is "use /chestshop buy <price>" beyond that nobody knows why a decimal place doesnt work.

Please provide the information requested in the issue template, especially the exact server and plugin version, as well as the actual shop sign that you tried to create because decimal points are definitely working when used correctly.
